Pretty fun game. You have some great potential with the movement, the wall running is well done, and then adding the grappling hook feels great. I managed to beat the 2 bosses, and jumping around the platforms with the grappling hook in the 2nd boss was pretty satisfying when I got it right.
The bosses felt a bit spongy, mostly because they move around a lot. You can't hit them that often, so they feel like they have a lot of health. However, them moving around so much forces you move a lot too, and I feel that the movement is the selling point of this game, so it's probably fine. Overall, a pretty nice game, good job!
