Very well put together. My favorite things in no particular order
- The level transitions
- The freeze-frame when bonking your head
- The impact sound effects
- The slow background parallax
- Physically pressing the buttons in game
There's a lot of character in this game.
A couple nitpicks.
- I wish there was more to the gameplay. Having some sections of more conventional platforming to separate the really fun falling mechanics would be nice
- I wish there was a fail state or downside to playing poorly - I can bonk my head as many times as I want with no side effects. If you implement some conventional platforming, you could have the number of bonks affect the responsiveness of the controls.
