I can see myself becoming bored with this game. It would be such a great game if there wasn't an add every minute. Sometimes you will be in a level and it will just take you to a add plus everytime you want to retry you have to watch a add first. Sadly I think this is another game where they havent got the balance right and will lose players because there is more adds than game time.

The game would be good if it weren't for the constant purposeful forced need to watch ads. The levels are geared up to ensure you can't complete them without using "special" items but those items are not easy to get. Even when one might have multiple "special" items collected, the game makes you use them all, then you still need to watch ads for more item to complete the levels so nothing to do with skill. Its only objective seems to be to get the player to watch ads. Deleted after 230 levels

Claims no ads, yet there are so many it's annoying. Also built to pass levels by chance or you have to use special item, you don't have. At times you think you unscrew all bolts and the part is still holding, not sure if it's a glitch or supposed to be like that. Same colour boxes loading one after another, you literally have no more bolts to choose, so either forced to use special item or fail the level. Deleted it after 11 levels, too annoying.
