Hello back fellow Godot dev !
I find your game pretty polished too ! The light effects are pretty cool and make the overall are shine ! The gameplay is very well introduced and this is very good, a lot of jam game don't take time to introduce mechanics even though it feels so much better when it's done ! The 3 last levels which starts to be harder are nice but they are very similar and I wished they weren't but in the time constraint that's totaly normal ! The animations are well done and the particles are always well placed. The only thing that really bothered me was the jump, it felt somewhat odd. Maybe put more control in air or work on the jump parabol a bit more ( for exemple the ascension parabol is generally wider than the fall one).
Anyway good job. For me, it's clearly one of the better games of this jam !
