I love the premise. I would've just had 1R+1G+1B tile per stage if I had made the module myself, so the module ends up a bit too error-prone for my liking even post-nerf.
Solve music is an absolute banger and functions as a great bomb defused music if it was your last module.
I also wonder if there's some way to come up with a fairer way to salvage the module than just the binary. If it were me, I'd have the wrong tiles flash up for an amount of time. If you miss by one, that's easy. If you missed by a bunch, you're going to suffer, but skill can make a difference.
