Factory Balls: A game where you are trying to match a certain paint pattern from a model using masks and various tools, and figuring out which order to use them.
Good game - graphics, music, interface, etc - everything is excellent, and I'm only about 20 levels in so far...
If you enjoy this type of procedural challenge, I'd also recommend tracking down the old Eyes Maze Grow games, once you've finished all the factory balls
I remember playing this game way back when the internet was still young. Thank you, dev, for this revival!
