Nice work! Creepy soundtrack and satisfyingly squelchy roach-squashing effect.
I feel that you could bump up your movement/animation speed quite a bit... it can be a bit slow getting to where you want to go. Also maybe add some more colliders so you don't e.g. walk over your table or bed :)
Well done for getting it to the submit stage!
Edit: oh, and set your game name in the installer (it currently reads, "GameMaker Game" or similar).
