I'm impressed!
This one was one of the greatest platformer games I have played considering this jam's submissions, and it is always lovely to see a fellow Godot Engine developer!
First of all, I liked the opening of the game and the polish elements in general, but they could be improved with just a few tricks! I'd suggest you take a look at "lerp" functions in Godot and experiment with them to add juice to your game. Apart from those, the game works as intended, so I think you've done a great job mechanics-wise!
Solid entry, good job!
