Hey there! Just played your game and thought it was a nice cute platformer :D
I loved the pixel art a lot and probably one of the best aspects of the game, it was super neatly designed so great job :D
The windmills was a great addition as the theme, I would suggest make it a bit more white so it's more understandable that its a foreground object
Here are some points of improvements:
- This game definitely needs coyote time. I think that's an essential control for any platformer because it make the platformer feel better. Right now your game has potential, if you add that the game would feel a lot better to play
- I might just be bad at platformers but just a bit more checkpoints might be nice, because I thought the checkpoints was way too far apart
Other than that its a nice cute platformer so great job :D
