This game's presentation undersells its gameplay, it's really fun! I wasn't able to beat it since I got stuck at the part after the rockets with many single-tile stairs to climb up. The level design is good; most of the time you can save yourself from falling with a well-timed grapple, but the threat of losing a lot of progress is always there.
I found the physics to be occasionally frustrating. Sometimes I would bounce on a 45 degree angle and not be able to grapple, making me lose progress that I feel like I should have kept.
