It's a creative concept for a game and has a lot of charm to it!
It's a shame that I'm bad at puzzle games, so I struggled quite a bit and was only able to clear 4 or 5 levels. The double jump felt very unresponsive and didn't always register due to the very tight time frame that you have to do it in. It might have been a better idea to let the player double jump at any point while in the air, instead of only at the beginning of the jump. Also, jumping while holding the ball automatically releases it, which lost me the game many times, or just softlocked me.
The game also ran very poorly when I was moving, even though I downloaded it, which made i much harder to play. In all honesty, that was the most detrimental part, while most of the other stuff could be skill issue on my part.
Anyway, good game with a lot of potential!
