The number of clicks the game says I took isn't always right. I finished both levels 6 and 7 in four clicks, but the game said I only took one click each level.
basically, red kills red, yellow kills yellow, red kills yellow, yellow kills white, white kills red..if ball gains immunity by bumping a cloud, all abilities of all actors(even the wall) bumped by the immune ball are bypassed
I think the difficulty with the mouse control when dragging a piece will be much lessened if you take note that movement is locked to the z axis when you drag up and down, and it is locked to the xy plane when you drag left, right, forward or backward. You can only transition between these two by clicking a piece again and dragging to a new direction.
Piece rotation in challenge mode is now controllable by WASD or NUMPAD 8, 4, 5, 6
