This is a really clever idea for a puzzle game!! There's a lot of potential here a bit of polish and tweaks could boost. One thing I thought while playing that could alleviate some frustration would be if hitting R reset you to the last green control zone instead of starting the room over. Although, now that I typed that out, I realize that could break certain rooms so maybe you could use a different button for a partial resent and keep R as a full reset? Idk. Also, the audio being so hard panned threw me off for a minute lol.
