This is pretty darn impressive for a game made in three hours! It gets pretty darn hard later in the game, but I still had a good time beating it! 

Really great works with only 3 hours

wow ! you did great. It's has a "Celeste" feel : difficult but doable, very well balanced and thought. Clever level design.

3 hours!  nice concept, you can see the potential is there!

Seconded - making this in 3 hours is wild. Super clever gameplay loop, and the player handles really nicely actually! I can't say I felt a need for variable jump height, but it just feels right haha. I got stuck a few puzzles in as it was a bit too precise for my liking though. Great work!!

In 3 hours it's impressive ! The gameplay idea is nice but it becomes quickly difficult haha! 

Cool little game :)
