Though this is a common take on the theme, I think what you've got is a pretty cool concept! The art is also very stylish as well, it reminds me of some old flash games that I used to play when I was younger. The sounds are also quite satisfying to hear. You've got some good UI going, and I'm impressed with how you did the lighting.
Although the general platforming movement is decent, it feels a bit too restrained even with the rope. The rope felt heavy to the point where making some jumps were near impossible. It was also slightly difficult to discern which platforms each character should be on; the colored light is very faint. Maybe next time if you're making something similar, have a completely different platform altogether so it's clear to the player where the end goal is.
This is a pretty decent jam submission, and with a little more polishing you could expand on this further in the future.
