How to Fix IGTAP Crashing on Launch and at VMAN Ending

Dealing with unexpected game shutdowns can instantly ruin the momentum of an otherwise addictive platforming session. If you encounter IGTAP crashing right when you hit play on Steam, you are certainly not the only runner facing technical hurdles. Many players experience IGTAP crashing before the main menu even appears, while others hit an abrupt halt during the deepest sections of the endgame.

Published by Gamersky Games and developed by Pepper Tango Games, IGTAP: an Incremental Game That's Also a Platformer blends incremental progression mechanics with precision jumping on Windows and Linux. Players amass an army of clones to follow tightly-optimised paths, generating massive power to upgrade production and movement abilities. With an overall Very Positive review rating on Steam (spanning 338 positive and 64 negative reviews out of 402 total), runners spend hours optimizing routes, finding secret upgrades, and unlocking movement abilities like wall jumping, the dash ability (Spintap), double jumps, refresh orbs, and zip movers.

Understanding whether your software is failing due to a DirectX issue or triggering an intentional narrative event will save you hours of unnecessary troubleshooting. This complete guide walks you through every verified fix for launch failures, explains the mysterious crash tied to the Vman speedrun, and details how to safeguard your hard-earned save files.

Understanding Why IGTAP Crashes on PC and Handhelds

To resolve your stability issues quickly, it helps to distinguish between a genuine software error and an in-game scripted event. Player reports on the Steam community forums reveal two primary crash scenarios: sudden crashes on initial launch and abrupt closures during the Vman trial sequence.

When launch crashes happen, players describe clicking the green "Play" button in Steam, watching it turn blue for two to three seconds, and then seeing it immediately revert to green without any window opening. According to technical player logs, this startup failure frequently ties back to rendering failures within the DirectX 12 core libraries, missing system dependencies, or corrupted game data. One player confirmed reinstalling no less than seven times without success, illustrating that simply redownloading client assets does not fix the root DirectX or dependency conflict.

In contrast, players who encounter the title shutting down after completing difficult platforming challenges in course runs are often experiencing a deliberate design choice by developer Pepper Tango Games. For instance, finishing Vman courses 1 through 5 unlocks progression achievements such as Deja vu, Getting Faster, Half done!, igtapithon, and Waow... so fast, leading directly into an ominous sequence that terminates the application. Distinguishing between these two situations ensures you apply technical repairs only when your system actually requires them.

Step-by-Step Fixes for IGTAP Crashing on Startup

If you are dealing with startup failures where the client refuses to load, standard reinstallations often fail to address the underlying system conflict. One player confirmed reinstalling no less than seven times without success. Instead, following a structured sequence of driver, runtime, and launch configuration updates resolves the problem.

1. Force the DirectX 11 Launch Option

The primary technical trigger behind startup crashes is how the Unity engine interacts with modern graphics APIs on certain Windows hardware. Crash logs collected by users highlight errors referencing D3D12Core, indicating that attempting to initialize DirectX 12 can cause an immediate fault.

You can bypass this issue by forcing the executable to run via DirectX 11:

1. Open your Steam Library.
2. Right-click on IGTAP: an Incremental Game That's Also a Platformer and select Properties.
3. Stay on the General tab and locate the Launch Options text field at the bottom.
4. Enter -dx11 into the box.
5. Close the settings window and launch the title again.

Forcing this rendering API bypasses the invalid address exceptions generated by DirectX 12 libraries and enables the application to boot normally on both desktops and laptops.

2. Verify Game File Integrity

Corrupted local files during downloading or updating can prevent the executable from running. Verifying your installation ensures every asset matches the server release:

1. Right-click the game in your Steam Library and choose Properties.
2. Navigate to the Installed Files tab on the left-hand menu.
3. Click the Verify integrity of game files button.
4. Allow Steam to scan and automatically redownload any mismatched or missing files.
5. Once the verification finishes, exit and restart the Steam client.

3. Install Microsoft Visual C++ Redistributables

Missing runtime packages can silently terminate an application before graphics initialization begins. Even if you run a 64-bit operating system, indie engines often require both platform architectures to handle modular dependencies properly.

To fix potential dependency conflicts:

1. Download the official Microsoft Visual C++ Redistributable packages.
2. Install both the x86 and x64 versions on your computer.
3. Restart your operating system completely once installation finishes to allow Windows to register the libraries.

4. Update GPU Drivers and Run as Administrator

Updating your dedicated GPU software prevents display crashes:

1. Open the Nvidia App if your system runs an Nvidia graphics card, or open AMD Software if you are equipped with AMD hardware.
2. Check for the newest available display driver release, then download and perform an installation.
3. Exit Steam completely once the display driver finishes installing.
4. Right-click the Steam executable or shortcut on your desktop and select Run as administrator.
5. Launch the game directly from your Steam library.

The table below outlines common technical symptoms and the corresponding direct actions recommended by players and guides:

The VMAN Ending Crash: Is It a Bug or an Intentional Feature?

Numerous community threads express confusion over an apparent IGTAP crashing bug that occurs immediately after completing late-game content. Players reaching the end of the Vman speedrun sequence report seeing their screen flash white, followed by the game immediately quitting to the desktop. Some players tried the sequence multiple times on laptops, desktop PCs, and the Steam Deck—even testing while disconnected from the internet—only to find the game consistently crashing at the exact same moment. In one speedrun attempt, a runner was able to bypass the movement block when reaching the credits and took the zip mover on the left, but the game crashed shortly afterward regardless.

Community discussions and player experiences confirm that this specific crash is completely intentional. When you successfully navigate the trials and trigger the secret milestone, the application displays a brief, ominous message written in Latin before deliberately terminating itself.

The Latin text shown briefly on screen reads:

Quaeso ad locum generatorus redi: Ulteriores decessiones ruina violenta punientur.

Community members discussing the phrase note slightly different translations depending on tone:

• "Please return to the generator’s location. Further departures will be punished by violent ruin."
• "Please return to the place of origin: Further departures will be punished by violent destruction."
• "Return from whence you came, lest you face a violent end."

Seeing this screen grants the official Steam achievement Quam Formidolosum, which describes viewing an ominous message within the Vman speedrun. Players on Windows laptops, high-end desktop rigs, and the Steam Deck all report the exact same crash sequence. If you triggered this event and earned your achievement, your installation is working as designed by the developer, and no troubleshooting is required.

Diagnosing Error Logs and Protecting Save Data from Crashes

When you encounter genuine software instability outside the scripted story events, reviewing internal log files helps identify the underlying malfunction. Because the title is built using the Unity engine, detailed technical logs are automatically generated during every session.

Reading the Player.log File

On Windows systems, you can locate the diagnostic log created by the engine at the following file path:

%USERPROFILE%\AppData\LocalLow\CompanyName\ProductName\Player.log

Players inspecting this file after launch failures often discover the following specific exception:

ERROR: SymGetSymFromAddr64, GetLastError: 'Attempt to access invalid address.' (Address: 00007FF91538A40E) 0x00007FF91538A40E (D3D12Core) (function-name not available)

This explicit error confirms an unhandled fault within the DirectX 12 graphics subsystem. Whenever this signature appears in your Player.log, adding the -dx11 launch command provides the immediate workaround.

Preventing Save File Loss

Unexpected hardware shutdowns or sudden crashes can occasionally corrupt your campaign progress. In early community threads, players noted losing several hours of progress after a computer crash occurred while the game was running post-game tasks. In one reported case, a player who had logged 6 hours reached the ending and was tackling post-game content when an unrelated computer crash caused their save to reset entirely upon pressing continue.

Investigations revealed that the game automatically autosaves, but if an abrupt crash occurs exactly while writing progress data, it can leave behind empty files. When the game boots up next, it detects an empty save state and prompts a fresh run from the beginning.

In official announcements, developer Pepper Tango Games deployed Day 1 bugfix patches targeting crashes on save and stats jumbling, alongside fixes for missing localisation strings, a simulation bug where watts were gained on the pause menu before launching, and minor adjustments to spike hitboxes. Further updates followed, including Hotfix #1, Hotfix #2 (which made omni-dash optional alongside endgame balance patches), and Hotfix 3 for technical improvements. Additionally, an official notice clarified that demo saves do not transfer to the full game. If you experience an unexpected crash that wipes your file, the developer has assisted affected runners by providing replacement save files.

Official System Specifications and Stability Recommendations

Confirming that your PC meets the official system specifications helps avoid unexpected performance issues when managing large numbers of clones, purchasing atoms, utilizing refresh orbs, or navigating courses in reverse order for achievements like Reverse Current.

You can confirm your setup against the official requirements published on the IGTAP: an Incremental Game That's Also a Platformer Steam Store Page:

Minimum system specifications also list a 2GHz processor. The game is priced at $8.99 with a regular price of $9.99, spanning genres across Adventure, Indie, and Simulation. With single-player optimization and support for full controller setups (including DualShock and DualSense pads), Custom Volume Controls, Save Anytime, Steam Cloud, and Family Sharing, keeping your system updated ensures that currency farming, clone pathing, and trial speedruns remain completely stable across all 20 supported languages.

Frequently Asked Questions About IGTAP Crashing

Why does IGTAP keep crashing as soon as I press Play in Steam?

This startup failure is commonly caused by a DirectX 12 initialization conflict inside the engine. To prevent this IGTAP crashing loop, open the game properties in Steam, navigate to the General tab, and input -dx11 into the Launch Options field. Installing both x86 and x64 Visual C++ redistributables and updating your graphics driver will also resolve launch freezes.

Did my game break when it closed after the Quam Formidolosum achievement?

No, your installation did not break. This abrupt crash is an intentional fourth-wall-breaking event built into the Vman speedrun sequence. After reaching the credits or ominous message area, a Latin warning appears briefly on a white screen, and the application closes itself automatically while awarding you the achievement.

Can a crash cause me to lose my save progress?

While the title features autosaving, an unexpected crash occurring while writing save data can result in an empty file, causing the continue button to load an empty state. The developer addressed save crashes in the Day 1 bugfix patch, and players experiencing corrupted files have been assisted by the developer with replacement save files.
