Very addictive game!
Wow is it hard! It took me a good five minutes to figure out level two, but it never stopped being fun.
The mechanics are very unique, there's some really good ideas in this.
I did notice two problems, however. The graphics for some reason turned out very blurry, which takes a little away from the game, and the third level seems impossible to get through. Because the fireballs spawn all the way out of the shooters, if you don't get timing just right, you're toast.
All in all, an incredibly well thought out game.
Thanks!
