very cool mechanics! i really like the idea behind this game, grappling hooks are fun to use and i really liked playing around with the physics :) i think unfortunately one thing that really holds the game back is the lack of mouse sensitivity options. the default mouse sensitivity is tuned really low and it makes it feel a bit difficult to aim at enemies in more twitchy sections. the music is nice, but it gets a bit repetitive and imo does not fit the game too well...
despite everything though, the levels flow super nicely, and i especially love the gameplay of chaining together enemies while not having touched the ground once. destroying enemies is super satisfying in this game. i think this game could be quite special with some more polish put into it, i love these kinds of games :)
