I really really like the simple pixel art, the character looks so cute and the effects (dust trail, hookshot, etc.) really fits well the theme and the game. The Celeste inspiration got me hooked for sure.
Control-wise: Not sure if it's just me, but I wish the hook was on the keyboard. Like, I'd feel more comfortable to control the movement (WASD) with my left hand, and jump/hook with my right hand (maybe I'm too used to a controller setup and/or Mario-style controls). It felt really weird to me to have to move AND jump with my left hand and using the hook with myright hand). Not sure if I explain my thought correctly! especially when the game starts to become fast pace, it was very hard to quickly move. Maybe it's just me though! I could probably adjust after a while, but my first experience was a bit frustrating trying to figure out the controls!
It's a minor thing though, in general, the game is pretty fun :)
Great submission, gg on your game!
