Great game! The levels get harder and the items keep moving around so you can't just memorise where each item will be. On the tougher rounds you might need to purchase additional "helps" but if you just keep playing the level a few times you can actually eventually clear the level with no aid. We play it on the ipad so there's more screen real estate to play with. On the phone might be a little too small to find the tinier and harder-to-find-items.
