Pretty good
It was actually a pretty fun game. Wish you had lives, but that just adds to the difficulty, which I enjoy. I do have to say that after the first three games when I went to play again and an add was supposed to show up none did. So I had to shut it down then open it again. I prefer the focused shot but having a choice between them all was a nice idea. I would have also preferred if you had some sort of power up to make each shot faster, or some sort of upgrade system to that sort.
All in all, it was a fun game that I didn't have many problems with. I'm second on the leaderboards, for now :)
