Quite good, and very difficult. I do wish the corpses disappeared after a bit, though. On the level where the purple thing was introduced, I died so many times trying to use the gun to move upwards that I could no longer see my character under the pile of bodies. I'm not good enough at platforming to finish, but the mechanics and how they were used in the level design for the levels I got to were great!
Edit: I can't get past the punching glove level. Honestly, it's probably just a skill issue, but the dash doesn't take me far enough to pass all the spikes, even if I wait to fall a little then boost. I'm also confused on what the punching gloves do, since I thought they would give me an extra boost or something, but nothing seems to happen when I hit them. Anyways, I'm gonna continue trying later, bc there's like 100 of my corpses rolling around on that level alone.
