Overall not a bad entry but several issues:

• The camera was really annoying until I found a setting 'New Camera' to turn it off. It would be nice to have it off by default if it's experimental and unpolished.
• Character is very hard to control with the sliding. I understand that it's a part of the core gameplay to properly time jumps with respect to sliding but in the current state it feels like you're fighting against controls and not mastering them.
• There's a lot of situations when you need to drop down and you don't see where you'll land and you land on a trap and lose a lot of progress. In a game where it's all about precise jumping this is extremely punishing without being fair.
• It has nothing to do with the theme of the jam.

Regardless of the issues above I think with some polish it could be an interesting game.

Interesting game, I found the movement for small jumps to be a little difficult along with the lag that occurs when you want to move forward. It felt like i had to plan my movement way in advance so that I could properly make jumps and such. But the game has a very unique look, good job.
