The game is great
But it's not perfect.
**On the plus side, the game play is addictive, the level ups and ranks are great RPG elements that aren't overly complicated. I always feel rewarded when I reach a new rank.
**The music is also pretty good. Most games have music that loops and gets annoying after while, but this track doesn't bother me at all, and it fits very well with this game.
**The visuals are pretty cool, not the best, but they get the job done, and I know what's going on.
On the other hand, I agree with Dragonblade's sentiments. I understand making money with games, that's actually a good thing, but don't expect people to pay money for all of the features that should be earnable on their own.
Everything should be packaged and available within the game, then you separate the premium features with a separate release. That way we don't get surprised when we find out useful upgrades are only available through some pay and play site
and if you want to do that, you should use something like the i-phone, wii-ware, or PSN. Or batch it together with 5 or 10 other flash games, so at least you'd be getting your money's worth.
That aside, the game play is fun, though on hard mode, at one point it becomes pretty much impossible to defeat the 75 level challenge ( like around level 41), even with 5 fully powered supermonkeys. The challenge begins to become unbalanced in the games favor. The only way to beat it, would be to get points from that site, and arm yourself properly.
*** So all in all, great game, addictive gameplay, pleasant music, however, I would lose the payment system in the following games. The in game payment system is fine, but paying actual money for in game points isn't going to sit well with anyone.
