Below is my feedback. I submitted too.
- Gameplay: Great job on your gameplay loop. I could see this mini-game going well on mobile. Easy simple jumps and using kinetic energy transfer from jumps/heights.
- Theme: Cute game and nice of the pixel packs for your level designs. Your game vibe and style reminds me of Ebb and Obb, a cute platformer game with short stubby creatures. I think you could get major inspiration from that game.
- Audio: Clean and clear. I feel and sound like a waterdrop when I jump. Sounds in the game pleasing to the ear.
- Level: The ramp-up is well-thought out. I've played games where the first level is brutal and unforgiving. I love that you give players safe space in the beginning to run, jump, explore .
- Performance: There is some lag here and there on some levels and at cutscene moments. Maybe tweak some scripts here and there.
