Due to repeated feedback that people want the vanilla style orientation i made the following adjustments:

• Ctrl + LMB triggers Build2Me with the orientation of the targeted block
  
• Alt + LMB triggers Build2Me using the orientation of the player (looking direction)
  
  If you changed the default keybindings of the game, all i can say is: the stars dont align very well for you (due to the lack of an ingame keybind system)
