Wow... this is super beautiful. Animation is absolutely great.
I like pixel art just fine, plenty of exquisite examples around, but I'm glad you chose this style to make your game. I not only prefer it, but is also quite rare to see a platformer made with this type of linework. Makes it more unique, I feel.
In any case, great work. I'll try to remember to come back in a few days when I finish the game to comment on the gameplay.
Happy New Year 2025! :)
