I had a lot of fun with this game, but I couldn't beat it. Some of the jumps feel tedious rather than challenging. One thing I think might make the controls feel better to me (in my opinion) would be to not require the player to hold into the wall. I had a hard time getting my hand to cooperate with back-to-back-jumps that needed me to press opposite directions in quick succession.
But with all that said, I did have a good time until I got stuck. I put a solid 15 minutes into this game. I really like the timer, by the way. I wanted to put one into my game, but ran out of time and was afraid to change to much toward the end. But a great game, overall -- with a little more polish, this will be a solid game even outside of a jam context. Well done!
