It's a fun game. There is a particular strategy with which you can absolutely annihilate the monkeys, and every other strategy you get slaughtered. I was having a real tough time with it, but then I sat still for a second and thought about it. Then I came up with a decent strategy. Then I just watched as the giant army of monkeys got absolutely bombarded by an ungodly horde of sentient bananas.
I don't love having the two options for unit types because the two aren't balanced at all (the $10 banana is objectively a better value per unit currency than the $20, and there really isn't much of a niche for the $20 to fill because the field of battle is so small). But otherwise the game is really fun.
And the game is adorable!
