The game looks and sounds very nice. The platforming difficulty is fair, not too hard yet not too easy either. I think you did a good job on the level design! The game is a bit short, but it's alright given the time constraints. I also noticed that you spend time doing ledge graps, which I think is actually quite hard to pull off nicely, so kudos for even trying. The intro is nice too.
Anyway, for some criticism, I'd say the game suffers quite a bit by having no sound or effects when the main character is taking damage. It feels like suddenly you've died when the last second you still got full health. It doesn't help that you are being damaged by the spikes even before they stick out from the ground. That seems quite unfair if you ask me. This also applies to the enemy at the last of the game, and after a few tries of beating it up but to no avail, I decided to run past it and got a win instead.
Anyway, going job for making this game. Keep up the good work!
