Music sounds great! The art style is super cute and clean!
The number on the web blocks are a bit hard to read due to low contrast:
I think adding a prompt to press shift while the character is on the platform would be great!
The game is super fun to play! Building and swinging a round feels great. The game looks polished. I adding platform checkpoints would be nice! I managed to make it up mostly with the little blocks and swinging.
Overall a really lovely game and adorable main character. Great job!
