Nice, I like how you evolved the gameplay, and the music effet on color change is really nice.
Perhaps some your puzzles may need to be revisited, some times they consist of just getting the right color for a key, then getting another color for another key until you found them all, and don't give you too much to think about, but there are some that work much better.
Good job

I wasn't sure about the music effect, because it sounded better in my head than later in practice, so it is good to get another opinon here. I think I know one or two levels, that fit your description of getting another color for each key, and I get it. I was running out of ideas for the basic mechanic and I would have liked to create some more levels with the lever mechanic and maybe other new mechanics (a orb that makes you white again? mixed colors?) but ran out of time. But I hope to rework some levels and create new ones, in a few weeks.
Thanks for taking the time for the elaborate feedback and your kind words.
