Hello!
Just a minor bug report here, in the second area of the game (the purple, grassy area with the green and blue sky) there is a bug on one of the ledges leading to the save point. Jumping onto the left-most block on the ledge (two ledges down from the rocks) will completely softlock your character and make you unable to move or jump back down. The only escape is to reload your save.
Other than that, loving the game so far!
