The gameplay and idea are quite unique and fun! I like the concept of having to maximize the speed bar in order to jump higher. Also, that cat is cute.
I just think that you need to add some details to what's currently in the game:
- Some texts are blurry and can get optimized by using the TextMeshPro component.
- The sheep has no animations.
- The fences have no collision.
- A game gets significantly more immersive if you add SE's and a BGM.
Another advice that is not related to the game itself, is to build your Game Jam games in Unity WebGL. This way, people who don't feel like downloading files (which is a majority, I believe) will definitely play your game!
Lastly, finishing a game in just a week is really hard, so congratulations for getting past this challenge!
