It free. Its somewhat fun. But its not ready to compete with the likes of Monster Mayhem which this game clearly is inspired by.
The mechanics are off a bit making swiping difficult. That and if you are not perfect in your swipe and have enough power (which runs out way too fast) its game over.
Shows promise but its not ready for the app store. If you have a buck get monster mayhem. If not then try this for free and bring your laser level so you can swipe with unforgiving precision trying to play this.
