Yassss another Godot fellow!!
I really loved this submission, very polished, I loved the music and how it fades to another according to the area you're at, I managed to do a similar system and the final result is very pretty, congrats.
The "checkpoint" portals are so creative, very nice touch.
I wish it had a little faster walk though, it's too slow, maybe default speed could be the sprint speed, then the sprint power could be a "dash" ability (but this implies changing a lot of level design).
I managed to get sprint, double jump and glide (but then got stuck). Looking forward to finishing the game!
