This is not a negative comment but I have only one specific example of a control that is NOT intuitive .. er.. to me anyway: the left click to place, then hold-left-mouse-click to rotate? sometimes things get stuck diagonally after this or revert to aligned-to-vert/horiz position and i have no clue why this occurs.
Love the game, so cool. I mention only in hopes that it might help make a great game even better.
Hmm, I will check that out. I do have an intentional system to "snap" rotations to 45 degree increments...but that is only if you use the keyboard controls E & R to rotate.
This is very helpful though, and I really agree that the node should be rotating to the mouse once it is placed. I will try to get that in soon!
