I can't play the game... It says something about a JNI error, or something...
Can I rate based on the screenshots and comments alone? I don't think it would be fair but I'll give it a shot...
Edit: Okay, I downloaded the fixed version and can play now! It seems fine, but I could never get enough money to do anything... maybe I just don't understand how these turrets work well enough, but I feel like the enemies should give you a bit more cash.
I also overloaded a turret with 6 additional power supplies. It was glorious! Kinda wish there was an explosion animation after it detonated
