I thought this was a really cool game because you had so much control over your environment. At first I thought you were supposed to advance onto another level, but it just kept going to the same level over and over. I'm going to assume that was caused by how it was just the same thing. I'm glad there are upgrades. It seemed like there were too many enemies for one level. I liked the intro where you set the gas on fire.
I thought the whole game might be like that. It is a lot more fun that's it's like what I didn't think, though. I appreciate you continuning to make great games. The straight forward gameplay really makes it for me. Anyone who's a fan of shooters should enjoy this.
