This is a really nice and challenging mechanic. Instantly understandable but with lots of intricate possibilities. Just make sure you have a smooth difficulty curve! And keep the levels small, because otherwise the solution space is just too big (imho).
I'm looking very forward to the whole game, this looks really nice!
This was cool, Star Battle² !! Also I didn't know there was a puzzlescript fork with mouse support, neat!
