Screen too small, controls unresponsive.
Can't really see too much on such a small screen, and it doesn't seem to understand when I'm hitting something and when I'm not. I can fire on an enemy, have them dead-on, and it's almost a toss-up whether smoke will come from the gun or blood will come from the enemy. Also, it doesn't seem to matter if I'm mashing the mouse button or being more careful about it.
It seems like it needs a lot of work.
