Really visually appealing game. Very easy on the eyes! The platforming feels nice and tight too, with good fluid momentum. Nice wall jumps too, they work and feel just how I would expect.
I would like a bigger view port, I don't know a whole lot about Godot engine but bringing it to 720p would be excellent. Of course you were pressed for time, but some music and small particle effects would go a long way!
I hope you consider making more levels post jam, this is a very good effort.
