Really great, but...
Great game, absolutely addicting, fast paced and just all around fun...but i have two suggestions to make this game a bit better.
1. I dunno if i just couldn't find it, but a graphics quality control would be good to help with slowdown.
2. It was really hard to see what direction i was firing with the square reticle, and half the time the screen is covered in squares. Maybe a diffent sized or shaped reticle to make aiming a bit easier?
