love the app but...

i love this game. i play it all the time when im bored. my high schore is a bit more then 2 million so i have unlocked all the borers except for THE NINJA. i try using the zen and Black Devil boards but they are very touchy and i can rarely land any tricks so all i can do is gring and hope to make it to 3 million but i always run out of time. all the other boards before the Zen board works just fine. im not sure if making the Zen and Black Devil borads very sensitive is to make it challenging but it ruins the fun for me. others might like the challenge but not me. but this game is fun
