i also think it may happen because OpenAL32.dll is absent, so users have to find their own copies of this dll. im not sure but maybe they differ which causes errors. but you said that creating window crashes your program and OpenAL32.dl is related to sound, so that might be not the case. anyway if you post your code on github then i think some people who know WinAPI will find the reason

Ok now it works :) You should add some sort of indication, what you have to do at the start of the game. There should be a way to close the game, because I had to press Alt+F4 to get rid of it. I couldn't do it any other way, because the mouse cursor was stuck in the jail. Also, I didn't understand why the game had reversed text, but otherwise, a cool idea.
