Really cool that you made everything yourself, the art, code, sounds and writing! The writing is really fun, the dialogue made me laugh, especially the costume choice haha. The monster looks cool too.
The jump scare sound was really loud for me though, turning it down a bit would still give a good scare without hurting your ears. And honestly, if you like this game, you should keep working on it, whether you win or not!
Super nice that you still submitted with an exam to study for, well done!
