I like the idea a lot! Routing the colors is fun and has a bit of challenge to it. The first time I merged 2 together was a really cool feeling. I did have some trouble understanding the UI and how to pick which piece to use.
I am happy you liked the idea. I was aware that UI was clunky and unintuitive, sadly could not find a good solution in time. I was more motivated to increase level count as well :)
