Thank You for playing my Game and Reviewing it, I really appreciate that.
The Jump mechanic in game checks the distance above you when you press jump when ceiling is near you can’t jump, i think that’s why sometimes double jump rooms detects a ceiling and cancels the jump.
The Star/Ball movement is pure physics based but i applied some limits to speed and momentum, that’s why movement feels off. I try to fix that ASAP but currently in jam edits are not allowed and i need more reviews to continue improving the game.
