Do not buy. This is barely even a game, and most of it is physically impossible to play.
When the level is functional enough to even play, you can beat it pretty much by tapping on the first thing you see, without ever really knowing why that was the best solution. Some puzzles can occasionally be solved by guessing but it shouldnt be the first guess every time. That isnt a game. Its a boring movie that pauses itself every 30 seconds so you have to hit play again.
But that doesnt even matter because you cant even hit play in the first place. The navigation control is so astoundingly bad that I cant move past the 6th level because I cant even get close to the bomb to start working on it. The "move forward" button doesnt work at all. You just sit there tapping your phone over and over accomplishing nothing while the timer runs out. Why is walking closer to the bomb even a necessary step?
