:D This is super fun i love it, It's really neat coming up with different strategies to move things around!
My only feedback are similar to a previous comment, where there's no real way to evenly make the different colours, so you can't really balance it and make the most efficient machine. It would also be really nice if you could stack or combine the smart cursors in some way, as they are now it's kinda a pain having to drag like 10 of them off the same machine if you want to move them to another?
But other wise great job!!!
