Hey there!
I think it needs something extra to be a new game concept. The "connect the pipes" game has been around since at least 1989's Pipe Mania and this is the exact same concept with updated graphics and interface.
This is nice and polished although turning the pieces was a little slow.
Maybe add a puzzle element to it... have multiple end connections available in a room and allow the player more than one option on what room to go to next. That would be a good way to introduce various power ups to by-pass obstacles in certain rooms. It would require some careful thought on level design/progression and allowing players a path to revisit previous rooms.
