I love the presentation! Very cute artstyle and amazing polish with the camera shake effects, little dust particles when walking and the potion animations for different health levels. The sound and music are also very well done.
The gameplay, while satisfying, was a bit confusing for me. I thought that enemies took damage when touching walls (because of the hit effect) but I got one stuck bouncing between 2 walls and it did not die, so I ruled it out :p
I think it would be cool if instead of passive health restoration, small potions would appear randomly that would heal you when collected. So instead of idly waiting to get health back, you'd have to look around the level to find them. But of course that would take much more time to add and time is not something you've got plenty of in 48h jam.
Great job!
