I downloaded this out of curiosity and because i found the character cute and ended up being, no joke, one of the most compelling things i played today.
Alright, how do we start. There are some things that are FANTASTIC and others that are quite infuriating, hahahah
Right from the start i took a feel for the controls. The character has like, crazy mobility. It's incredible what you can do with him, and that's awesome. Every jump you have to think of your resources, two side dashes, one for each side, one extra jump and and upper dash. You can also run to gain extra momentum but that's just for the first jump.
All of that's awesome!
However, dashing with the arrow keys is really weird. It goes kinda against standards and it just makes me panic press and dash away to the bottom with dreams broken and feeling quite dumb. I'd suggest something like spacebar, or shift to dash!
Adding indicators of what jump resources you have left would be awesome too, like little arrows to the sides and over the character.
Another thing i'd recommend is a downwards dash, because the amount of times i fell due to not being able to stop the momentum of the side dashes felt kinda unfair, though again it was my own error.
Another really weird thing (though one that changing would mean a big rebalance) is how you lose all momentum when you dash. It feels strange, though i know some puzzles are designed around it. Though i do think it's important, as it would make the movement feel really satisfying.
Also, a sin of platformers: you always need to know where you can move. Maybe adding a key to look around, though it'd probably require for you to stick to walls too.

this is me and my friend playing the game! He speedruns Celeste, so he had quite an easier time with it. I just had to share it with him, he quite liked the mechanics! though he did point out quite a few things i added to the review.
If you want to polish and update this, hit me up: Stopsignal#2168 - I can help with art and animation and some tips, though i'd need time as i'm usually really busy!
Also would be nice to have WASD too, hehe.
