Helpful tip for those who max the bubble gum guy: You have a mouse button and a space bar. You can press both. If you have a laptop, you have a space bar and two mouse buttons (not including touch pad).
The game is probably a bit more fun than this, this is just a crappy flash. No, it isn't mediocre, the word is crappy. If anyone at least LOOKED at the advertisement, you would see that the game probably isn't like this crappy thing at all.
Don't complain about this being a copy. This is a genre of games (or subgenre). The genre is artillery. There are many games that fall under it, it is just that the most used are the tank ones. Other ones that fall under this are that one where you use the planes (I know it is kong somewhere), and also the game Worms (not a flash game). To those complaining about this being a copy of other stuff (I'm looking at you Asphaerimon), there are just so many weapons you can think of. Deal with it.
Quit complaining about the damn game >.< This was made by 4 people that aren't making huge amounts of money for it. If you want the game to be as good as Black Ops or Halo or something like that then you give them millions of dollars to make it.
