It can't be accidental that there are 69 code bits T-T
Anyway, surprisingly cool game! I thought it was just a typical platformer that barely fits the theme but the looping platforms were very unique, fun and challenging.
Also why did it take me 15 minutes to find a syntax error lol
P.S. The music kept getting quieter the farther I got, I think that might be because you used an AudioStreamPlayer2D instead of an AudioStreamPlayer. The difference is that the 2D version is based on position, so if the camera is far from that node the audio gets quieter.
