This is a greatly challenging game
Wow, this game is very fun and addicting. Game play was hard, but easily adaptable to although I didn't like that every time you send a score, you have to watch another ad to play again and repeat the process so it gets a 9. Controls are a 9 because I did like the simple way to fire kunai, but the specials were hard to use during a huge mob. Quality was fine for a pixilated game and gets a 10 though I didn't quite figure out slow motions were your opportunity to fire multiple kunai in that time. Story line is an 8 because doesn't really matter for a game that gets right into the game, but a good scheme would augment views and score. Challenge would get a 9 because it is not crazily hard and is kind of easy to adapt to after a restart. The game really is addicting mostly because of the high scores table and the urge to beat the game so it gets a 10. Game length is a 10 because it isn't too short nor too long of a game with a high scores table. It appears you have put a lot of effort into this using great music and enemies and that is great so effort get a 10. Lastly, fun is a 10 because a 10 is a fun...thing.
