I managed to get $NAN I must have broken it maybe? I got up to Dodecillion or something and boom. Brilliant game, I wish there was a lot more too it and less limitations with the money. 5/5 would $NAN again.
when you click this game, you think ... 'Oh wow a button hunt, i haven't played one of these in ages!' you get to level 3 and it finishes ... @Mastercool2 i have one word for you ... get a life or just grow up!! 0/0
The idea of the game is good, it's original, but the only problem is the controles... maybe you could move with 'WASD' and use your mouse to aim?? Just an idea incase you update or make a sequel. but overall it is a great game 4/5. :)
If you think the game is too short, then repair the balloon to 99% and then just kill the enemies :) it's pretty damn fun if you like a never ending zombie BATTLE!! lol :)
