Woooow, cool game!, nice music, the idea of a chess board in the down scene, the idea of energetic balls to translate to another worlds, that so look fine, I think, you need a start UI where you show the title , the goal and the mechanics  of the game. May be you could enrich your UI with a brief story about the game and your main character,  and could add buttons to play the game, settings like the sound volume and the credits screen where you can show the name of the asset creators in your game. With this game you shurely will win the jam.

Super cool game! The controls felt a bit weird, especially with the camera, but the movement was quite enjoyable. The levels felt a bit big, so maybe you could let the player move a bit faster, or be able to build up momentum in some way to traverse faster!

Bouncing around is fun! My only complaint is the world feels too big compared to the movement, so there's a lot of running and falling time and less of the fun clinging and launching. Ari looks fantastic though!
