I had a lot of fun playing this, great use of the mechanic. My only gripe was the jumping mechanic. I got stuck in the level with the 3(4?) pillars in the middle, I think I've figured out the solution, but whenever I jump it gets caught on things and I don’t go as high as I expect to and then get shot, maybe the player chars collider friction needs to be set to 0? Still good execution and a fun time, if a bit tense.
A level window, so you could continue on from where you left off would be neat so you could try certain levels again.
If you have time, would love to hear what you think of my game; https://itch.io/jam/gmtk-2019/rate/461074
