Really solid submission, very polished and good-looking! I spent some time getting comfortable with the controls, but after that it was nice! The map seems very large, and at the beginning I spent at least ten minutes climbing on the right and returning to the starting point... I though I was supposed to do that, and only at the end I read the note on the game page... If I may give you a feedback, maybe adding some indications for the player in the first part of the game would help the learning phase :)
Besides that, this is a great entry in this Jam, congratulations :D
