Pleasant minimalist graphics and music, ok controls
Some critique:
Save points were too sparse/ misplaced for me (aka skill issue). You can't save at the same save-point again - if you die after picking keycard you're forced to do that again even if you stepped on pad.
For how chunky we are the movement seems too floaty and weightless. Landing particles could be more pronounced.
Didn't quite enjoy trying to land on one foot on the ledges - maybe the issue is too fast vertical movement while airborne or hitbox that is smaller than body (which surely is nice for collisions with spikes though) or how wide we are (or my lack of skill again, hehe).
There is no nearly no indication that the enemy is killing us or how does it do it. Mark shows above it and then we just die. I kept dying after opening the door - enemy didn't touch me, didn't shoot me - I thought it's a bug.
