I saved reality <3
For a second game this is very well made. The mood, nice use of fun physics, nice level design that didn't felt boring... and you even did your own art! You deserve more eyes on your game.
Somehow, your character looks like gudetama when holding the hammer x)
Small suggestion for improvement:
- Detect when your player is on platform and make it follow it (inverse transform), because when the physics goes crazy after a jump it takes quite a bit of time for it to stabilize. Attempting to jump on those jiggling platforms was a bit of pain sometimes as the player doesn't "stick" to them.
- During my playthrough, several time my character "grounded" state seemed to not be detected and I could no longer jump. Maybe that was a feature because the wall were now the floor? If so having a different texture for the wall versus floor might help?
