Sorry, I can confirm I know this is definitely the problem. I think of it as level 4, but I know what you mean, things in the game are multiplied by a variable called GameSpd, which is like delta_time, only it's multiplied by other things such as whether you have the window open. This was supposed to let me make easy slow motion in some games but it entirely glitches them out. If you still want to play the game, I slightly edited that level and one other in the play in browser version to make it *possible* on lower framerates (*unless your computer is too slow*). However, to play that version you have to have Opera GX (a web browser).
