Wow this game might be the most ingenious way of teaching color mixing I've ever seen? Seriously, it was brilliant that you could not only solve each puzzle by fumbling around, which would then teach you the component colors of the one you're trying for, but that you could also go in knowing the color theory in advance, which would help you solve the puzzle more efficiently. Just excellent all around. And the presentation is incredible too! The menu transitions, the UI, the music... well done, a game to proud of. And I didn't even get to how integral the theme is!
My only note is that I'm not sure I got what level 8 was going for. I hit all the marks, but never managed to get a color on the shelf. Ultimately had to abandon that one. Didn't really detract though, great job!
