Oh. When I said the theme not being part of the game I meant the "Radiation" Theme wasn't part of the gameplay.
So basically, I was expecting the acid to poison you :]
i was expecting the theme to be actually part of the game
i was also a bit confused of the health bar..
Though, the controls are really smooth and I like how you just rotate around with the mouse!
I also couldn't really see any bullets from the turret. Overall Great game :] !
The controls and Speed of the game were the best part of it :)
