Cool concept, I like the use of negative space to go through platforms and having to remember when you're gonna switch from one space to another, the way you represented the time limit is also pretty neat with the view narrowing down as time goes by, although this can be quite hard to see where to go if you manage to progress but have few time left, and it didn't help with the bit of confusion that occurs from time to time when navigating the level.
Honestly it still is enjoyable even with these tiny flaws, and it makes for an interesting and original game, Congrats dude :)
