Yeah I'm sorry I fixed these things in the latest version like 2 hours before the jam ended but sadly itch didn't detect this new version I don't know why. I'll put it online once the jam is over if you want to give it a try, I'm sorry T_T
I had also added hints as to how you can get to the end of the level but well, it will be here after the jam ends.
I think I'll also set the screen effect as an option that people can disable. If you want to avoid the explosion bug, press R to respawn when you see you're going to die and you'll be able to play the game 'till the end.
