So good news and bad news; I'll start with the good. The good news is that you did indeed made a bigger map and the longer health bar makes fights last longer. The diversity of enemies helps out as well.
The bad news: you still have two major glitches involving sticky keys and unnecessary auto-fire. These are still major problems. But now that I think about it, they could be problems involving Unity and not completely your own fault. Every now and then, if I unintentionally hold the mouse button down and move the mouse, an icon appears that says it can't move anything, and that's normally when the auto-firing problem starts. I still don't know what causes the sticky key movements.
I will admit that you have improved the game somewhat, and will praise you for that. Still, the two major problems still bring down the rating a bit. None the less, I will say keep up the good work.
