I absolutely adore this game. I would love this is made into a full game after the jam is over! I'd definitely buy it!
I like that it seems as though you've took inspiration from a bunch of different great platformers. The dive and subsequent bonk from Mario Odyssey, the setting of Journey, the momentum mechanics in Celeste (that could've been from a different game, but it reminded me most of Celeste), and the main character looks like Claire from A Short Hike!
Honestly I loved this game so much! Thanks for submitting it :D
