I really love this game, it was a little disorienting at the start - I didnt see some of the hint messages on the left before they had disappeared and I didnt realize where to go initially so the first few runs were just being shot to death repeatedly. Once I got the hang of the movement with crouch jumping and kiting enemies, each run started feeling more and more like a speedrun out of this facility.
There was one section with a skill jump which I feel could have been made a little easier, it took me some tries to understand that the environment was an intentional ramp when I would slide off it at most angles.
I also like the pacing of unlocks and the power curve is fun too. Very impressive! :)
