Cute pixel graphics and I loved the upscale mechanic.
There's room for better feedback of collisions, sometimes I wasn't sure If I was hit or not or couldn't really notice how much health I have left.
But cool and clever concept. Very good work for a 48h project :)
Looking forward to your feedback and rating for my game as well: https://itch.io/jam/gmtk-2019/rate/462544
