You have to equip the ribbon to your gibbon and throw it at the giant woe tiger in order to defeat it - nothing else will work. The crab hints at it before the minigame.
Controls are not terribly responsive and occasionally buggy. The way that mobs spawn is very annoying - makes it difficult to survive when they spawn right on top of you. Playfield could be larger as well.
Good game, it's a bit more interesting than many TD games. The inability to select what color of gem you are buying, and the locked features are my biggest problems. Really, being unable to select the color is ridiculous.
As others have said, the bosses are kind of ridiculous, although not impossible. Just requires timing that is kind of too fine for the field size. Can't get badges to register.
Game is quite laggy on my old, crappy office PC with VoIP interface, remote desktop, and flash VoIP connection utility open =)
I wonder why. LOL THIS GAME MUST BE BAD!
