It's really could be a good game but unfortunately it fails like so many other games of this kind, It's a simple yet fun game concept it would be a 4* or even 5* if it wasn't for the forced ads every 30 seconds, I feel it would be more appealing to people if the Devs stuck with ads for rewards or bonuses as it is at the moment it's verging on unplayable unless you pay them to remove the forced ad system.
