This game contains some hidden surprises. Every now and then a UFO will fly past your screen, also gathering resources. Smashing this ship gains you the bonus of doubling your tapping power. Utilize this to quickly gather what you need and prepare for what may come next!

When you have got somewhere to go and the urge to build is strong, just take out your phone and play this relaxing game. Feel the accomplishments of building grand structures after a few taps!
