NEVERMIND! Of course I notice the manual and automatic option now lol
Ops lol
But I'm glad that you liked the game! Yeah, the placement mode change it's in the description, but I think its tutorial in-game could have been a bit sooner than it is.
But I'm curious though, how did you got stuck on level 3 with auto placement? It seems very straightforward to me, the shortest path to both buildings doesn't go above the wire limit.
