Ok, I made what I hope will be the last bug fix, I playtested it myself, but I don't see a white square anywhere.
All the cutscenes and controls work like I wanted it to, so I guess it is something on your end.
:/
It's supposed to be a rage game, so the controls were supposed to be hard, but I'll explain. W moves you forward in any direction that you use
if you use the A and D keys to rotate to where you want to go. Also the mouse shoots, and there's dark matter when you spawn in, then some when you go down to the left then go more left and you'll find the third one. Go right and up and you'll find the remaining 3 you need to go to the next level.
