Great fun! Feels really well polished. Nice work.
Game needs a pause menu & volume controls.
The progression of levels does a good job of easing you into the game and learning the controls; it feels good. I’d continue to work with it and add more obstacles/items to challenge the player.
I once watched a good YouTube video on level design (I’ll add a link if I can find it); the advice in how to give each level it’s own meaning: give each level a theme or main idea and play with it. For example: one level could focus on: FALLING
Hope that helps! Good luck!
