Very fun, and is NOT a ripoff.
Just made prettier. ONTO REVIEW. Fun, enjoyable, and a nice time killer. Though, perhaps you should've added an ever-lasting mode, for those that enjoy mindless killing without limit.
OH. And, since I'm a semi-nice guy, here's the download link for you. WORKS too! Just check the adventure section of http://freewaregames.co.nr/ If it doesn't work, send me a PM, and I'll see if I can find a workin' link.
Enjoy, enjoy, ENJOY!
