Great game! Especially since it only took you two days to make it. Its gorgeous visuals work great with the music and it fits the theme of the jam nicely.
In case you continue to work on it, here is a little bit of (hopefully) constructive criticism:
The strategy that worked best for me, was to stick to one side and just move in a straight line forward. It made going back extremly easy because i didn't need to remember my path. But it kinda ruined the point of the game and, after that, it was not that fun anymore. Maybe place some obstacles that don't move in the level so that the player has to walk more complex path.
The tutorial text at first made me think the game froze and it was a bit annoying that it showed up every time i respawned.
The controls on the turned passages are a bit confusing.
I hope i don't sound to harsh. But you said in an other comment that you appreciate criticism, that is a sign of true wisdom and i respect that.
Anyway, i really enjoyed your game and i hope you continue to work on it :)
