Very fun game, I found myself doing a few run throughs to see all endings! I love the level design and I love the controls even though I was a little confused on the jump/float mechanic, I had a blast with it.
There is no health bar or health indicator and that was certainly annoying but just shooting randomly and quickly seemed to be the easiest solution to prevent that from ending me too soon.
The only other thing I would suggest is adding a volume slider as the sounds were just very loud.
GG, thanks for the submission!
