It's alright, but nothing spectacular. The boss is pretty much a joke, you just hide somewhere where he couldn't hit you and you could hit him and it's done.
Final Ninja Zero (actually it is already released in AG but didn't shown up on the main page yet) drive me crazy, as I finished the game by spending hours dying over and over. Actually I can see the game can be beaten perfectly, not even losing one health, so I wanna someone post a speedrun video. That should be epic...
The producers were so cruel and demands so much skill to use a mouse and keyboard simutainously. I thought Fat Cat was bad enough.
