Nice game, has potential. I liked its progression, and the underground zen garden theme was very good. I loved it a lot.
Now, the controls seem a bit floaty, and sensitive to the slightest touch. I kept missing the jumps up top.
The character is a bit too slow. I'd recommend adding a running function. If not for puzzles, it would at least help reducing the time spent for returning back to where a player failed.
But overall, I liked the way it plays. Cheers!
