Really love the art, and ur Qodot usage also came out really nice!
I do not enjoy 2D platformers so I'm not trusting my critiques on how the game played but I envy ur art so so bad.
Your critiques are still valid regardless of your skill level.
Personally I think some of the level design can be tweaked to let the player learn the central mechanics without trial and error, but I just didn't get around to implementing it.
Glad you enjoyed the artwork though!
