Coastguard

It look snice I think, sounds good too. The gameplay and balancing needs alot of tweaking; First thing I did was upgrading one on accuracy and damage and speed to max, I never got hit by any bomb. Right now I'm only pointing at the end of the screen shooting. No suspense.

Really easy. I just sit there holding my mouse down by the left edge. Occasionally I press 1,2,3 to do a special because I get bored. There are three healing skills, what's the point? Do the bad guys ever hurt you?

Balloon Invasion is a better game. It appears to be a modern boat, but have there been any military blimps since WWII?

i think the difficulty of this game should be a bit tuned up. Right now it is way too easy and there is no strategy involved in the way you choose upgrades

calling this a stolen idea isn't valid. It's a clone, but that's all.
I'd like to see you come up with a game that isn't based off some other game somewhere.
