The game is a bit simple, but it's done well, and I can see this developing further into something more complex! I would have liked to have needed to match something other than just the colors (like the shapes), but I assume that was something on the planning board that there wasn't enough time for. Each joint being able to connect to multiple other joints (or not connecting to any of them) was a really good twist that added a level of interest that kept me thinking throughout! My one true complaint is that the sound only came out of my left earphone.
This is definitely worth continuing development, good job!
