Its a fun puzzle platformer with an interesting core mechanic :)
What i would definitely changed though is to change the physics of the game as soon as the transition starts rather than after. The way its done now makes the player punished for the right intentions that fail because of a game mechanic(especially when the game stops your acceleration midair, and you cant really regain it well), which leads to needless frustration.
Furthermore, the game is rather fast with some text being spread in the game world. I would rather if the texts did not disappear to let the player be playful with your movement and juiced up character feedback rather than to force him to stay still just to read a little bit of text that may or may not be relevant
Otherwise, it was a fun experience and a concept overal, i enjoyed it .)
