well... the game is really well done, is super polished, super fun, the difficuly is tuned with extreme care, the pixel art is awersome, the music... was ok, but... BUT...
It lacks a tutorial... (for the special orbs, at least...) because i'm a big dummy and i didn't see the commands in the description, i spended much time than i should have to try to understand how to pick up and use the special orbs (ok, the game is fairly intuitive, so the majority of people dosen't even need one so the lack of it is forgivable... maybe do a thing where the tutorial pop up saying "press LShift to pick up Jump Orb" only if the player stand close to the orb without picking it for 10 seconds)
