Hello @notIkibo, we're using one issue report per unofficially supported game title, so I've gone ahead and transferred this issue report to https://github.com/ValveSoftware/Proton/issues/2844#issuecomment-5846500970.
Hello @notIkibo, we're using one issue report per unofficially supported game title, so I've gone ahead and transferred this issue report to [#2844 (comment)](https://github.com/ValveSoftware/Proton/issues/2844#issuecomment-5846500970).
I truly didn't know. I saw the issue, but it obviously isn't crashing anymore so I made a new issue report for a new issue.
Can one expect a fix for an unofficially supported game? What factors decide what game is officially supported and what isn't? It's popularity?
Thank you in advance!

Symptoms
After killing a boss in stages 10/20/30/40, you need to input LShift+RShift in a different game state that seems to have a different input system.
Any button press is unresponsive (most - if not all other - of the button presses are disabled in that game state by design). The game won't progress unless it recognises the keys held.
On Windows, it works perfectly fine.
The game depends on Steam Overlay so troubleshooting grab issues by turning it off wasn't possible.
Reproduction
Speedrun the game until the 10ths stage and defeat the boss.
Interact with the staggered boss. (Game state transition)
Softlocked.
