Haha you are totally right, I didn't have time to fine tune the controls and physics so they are a bit iffy. It is sometimes hard to reach a ledge or avoid taking a power-up. Thank you for playing the game in spite of this!
The rush was mainly for the implementation part, as I'm new to Godot (and game dev really). I took a lot of time sketching ideas and levels at the beginning of the jam, so the levels were all ready to draw with tilemaps on the last day.
