Its a fairly basic monster-slasher game that doesnt require any money to play for extended periods of time. That said, you can improve your overall experience by making some purchases or viewing some videos, but its not mandatory, and you dont get adds shoved in your face every 2 minutes.
The game itself has a fairly limited landscape and equally limited cast of monsters to fight, but theres something about the simplicity of the fight, combined with the achievable goals that keep you coming back for more.
Its certainly not an exceptional game by any means, but its fun and good to pass time when you have a few minutes to throw at it.
Caution: I think I gave myself tennis-elbow from the repetitive motion of slashing the monsters... yet I keep coming back for more.
