Its really odd, and not my type of game, but its good! The idea works, the mechanics are well done and easy to understand would work very well for mobile (feels like the idea should already exist there). I'm mostly impressed how complete it feels, with a menu, countdown, music, sound effects etc. and there is even a extra challenge with the Earthquake for added flavor! Even tho I usually don't like these types of games, I actually played it a few times.
