I would have switched the colours, so being red shirt means red are solid (maybe an accessibility option to decide). I kept on messing up because the colours felt backwards to me.
This 3 block high jump  feels almost impossible, you basically have to glitch through the platform. And then there is another one on the left just before the flag!
It felt more like I was trying to fight the collision physics than actually trying to learn a game mechanic.
The music loop was too short so I had to mute it immediately.
I hope you don't find this comment too harsh, I still had fun even if it was a little frustrating. You should be proud you managed to make a functioning game in such a short amount of time. Good luck in your future projects!

Interesting concept. I had to stop playing right away because the music hurt my ears. I didn't quite understand the mechanic of switching the player's color (if it was timed or there was a button a I missed).

Congratulations for your submission, unfortunately it doesn't really fit the theme. This would've been a fun game on its own but there is just no "loop" element at all.  Also congrats for making your own music.

Cool to see someone's first game — well done! I like the idea of needing to time and continuously switch colours. Though, I often got stuck in a block, so it would be nice to get more of a push up onto the platforms. Then you could play around with momentum and physics. Still, excited to see your future projects!

the piano loop grew on me. quite frantic haha

is glitching through the platforms supposed to be the solution?
