also I think I'll add a fall limit so if you fall for too long the game make you restart. Cauz finding all infinite fall (particularly in weird zone) is a bit annoying to test :/
because of the optimisation made for the web version objects often appear after your cube when you fall at high speed, so it's kind of hard to add that. But if you encounter an infinite fall for now you can just press P to pause the game and click restart level.
