This is awesome! I spent a lot of time playing it it's really fun and chill. I think there's an issue on one of the later levels where it's wanting red squares but they never spawn? Also I dunno if the "detaching resets the link" thing is the best as it means it's really hard to correct and it's better to just restart the level. Perhaps that's the intention making it like once you commit to a placement you have to go with it? But yeah this could easily be tidied up and released it's great!
