Neat concept! The puzzle elements seem to be coming along nicely so far.
One word of caution–I’m not sure if you’ve accounted for this yet, but the red/green/blue switches might make your game difficult for colorblind players. It’s not an insurmountable issue though, giving them a unique level of value (lightness), adding a subtle pattern to each, or messing with the shapes a bit could probably help make it accessible. I would recommend thinking about it now if you haven’t though, since it would suck to finish the project then realize that it’s an issue!
