Currently encountred glitches:

After dying (encountered when dying because of instakill things such as falling in a bottomless pit) all the blocks in the level (or almost all of them) get separated and look weird.

Can't select the other music folder, the game crashes because of that, for some reason.

After dying, the music simply stops and has to be restarted.

The enemies die when they're out of the main first screen, for some reason. I am not sure if it's even the first screen - they just die outside of a small area sometimes, sometimes they die only when it's vertical, sometimes they die when it's doors. I dunno.

The goalgame can take place and glitch or stop in a room of the level itself.

Sometimes the game crashes when i try to load or save a level. Loading default level causes crashing.

Some enemies that are supposed to have abilities don't give any abilities.

Game crashes after Goalgame.
