Trash. The main game is good. I orginally rated it higher. Once you get into later lvs, and you still have to deal with the adds, you have to use your bonuses to win the levels. I get using one once in awhile, but not to beat every lvl. If you watch an add to get a free power up, it does you absolutely no good. You end up using it right off the bat and still can't beat the level. It's a complete trash game. Just wait until you get to the 700 lvs. Once power ups are gone, game is deleted
