Kinda fun, though the attacks as well as the enemy moves happen way too quickly so it's hard to keep track of what's happening. Also it's really difficult to tell in what order pieces attack if multiple are targeting one enemy, so that could be clearer. It kinda sucks that you can't cancel a piece's attack without breaking its line of sight as well. Finally, maybe remove the snarky comments in the level quitting menu, no one wants to be berated for using a utility feature.
Ok game, could be better.
