I really like this game, it's a super neat system! I had a lot of fun trying to figure out what shape I needed to place things in to be able to make black, and the music was really nice an hypnotic.
By reading the comments I can tell you ran into some problems, but this is really cool so far! What this game needs more than anything however I think is an in game tutorial. At the start I couldn't really figure out what to do, even by reading the in game help and upgrades. It wasn't until I decided to copy your screenshot with all the yellows to see what would happen did the game click and I did eventually get to 1k black. It was pretty intuitive after that, however I never figured out what the mixer upgrade did and to get to 1k black I basically just made the same machine ten times.
Your system worked so well that I was surprised when I tried the pictured setup and didn't get green.
Definitely keep improving this game it's cool!
