"because red is bad, or something like that I don't know art" is now my favorite premise for a game. (Seriously though, I have sat through so many long cutscenes where I'm like "yeah yeah ok premise and then I solve puzzles can we skip it"? This is perfect.)
It's short, but it's entertaining. I could imagine doing more with it (the green mechanic is interesting!), or just leaving it as a snack-sized game.
