The level design is the strength of the game with a good variation! Very cool that you have a death counter instead of reseting the whole game every time we lose.
Quick Suggestions:
- Reduce the confetti on the ground to make the player stand out more in the first levels
- Maybe the collision detection is a bit too tough and could be reduced a bit (the radius around the player)
- Add just a second frame to the player with hands and legs nearer the body and swap them every couple frames when moving
Well done on the Game!
