FOR FREE! ...As usual.
However, in the iOS Version it has a remove ads in-app purchase (and for several quirky, albeit unimportant features) for $0.99. Well, we don't "sell" the game, it's not Freemium or anything. The money is to support Trigger Project >w<. You dont have to pay, but if you do, we'll be VERY Grateful (Eventhough it's only $0.99)!
We encountered a problem with openFeint right now, so unfortunately there's no online leaderboard... Yet. As we try to fix the bug, we'll update the game later :D.
Enjoy! EDIT: CURRENTLY, SEVERAL USER EXPERIENCED BUG WITH THE GRAPHICS... WHICH WE DONT EXPERIENCE HERE IN THE DEVELOPER'S IPHONE... WE STILL DONT KNOW WHAT'S WRONG. IF YOU DO EXPERIENCE IT, PLEASE EMAIL US AND TELL YOUR IPHONE/IPOD MODEL!
