I like the idea of walking inside a clock and fixing the order of the numbers.
It took me a short time find out how it works, but after that I really enjoyed playing it.
A little thing that bothered me was that the music was pretty much on my left ear, the cause could be that you may have used an AudioStreamPlayer2D instead of a normal AudioStreamPlayer, because with an AudioStreamPlayer2D it sounds like the music is coming from a certain direction instead of everywhere.
But all in all, a great entry!
