Hello, Sorry for the late reply.
Thanks for playing. Yes, I was in a big rush at the end that I could not modify even this :D
For the door issue, it was a bug that happens if you trigger the spawner twice. But it is something that I noticed too. Also the spacebar resets the level, it was suppose to be a debug for me, that I forgot to remove XD. joys of a gamejam I guess :D
Thanks for the feedbacks on the game, i'll check the other bugs you mentionned with the screen shake.
