The aesthetic & sprite work was really nice, and I think you fit the theme nicely with the spin on co-op gameplay! Design-wise, I think it would've been interesting to have the green character take separate actions or have its own goal / room, because a good amount of the early solutions just felt like jamming them into a corner or bumping into walls to make it to the exit. I also felt that the timed mechanics (poison clouds & sliding blocks) were a bit frustrating when tied with the strategy-puzzle element, but I could definitely see it working with more refinement!
