It was cool to criss-cross those wires ! The presentation is very clean I like a lot the visuals of the game !
The 2 little things I will complain about are the fact that you can't undo one tile at a time, and when you create a mess of wires there can be situations when you may not reach correctly the node you want, you have to rotate a little bit more to access it.
Nice job for this refreshing take on the Flow free concept !
