Ninja Slash

5/5 for graphics and coolness. An army of pixel ninja attacking a castle, and a nameless swordsman wasting them all by himself? Nice. Shame it didn't have a nice upgrade+boss scheme, but still cool.

394 killed in time attack

Way too easy, I would suggest maybe turning it into a sidescroll platform game, then making some changes;
-Health doesn't come back when killing enemies
-Double jump
-Less enemies
-Levels increasing in difficulty
-Some kind of upgrade system

Good game, gets too easy in survival mode once you hit around 60 seconds. Slash kills more people than they hurt you so you stay at full health. Maybe lower the cooldown of Slash so you don't gain health to fast.
4/5

so hardddddddddddddddd

Wow, my favourite flash game on kong, no, ever.

5/5 for pixelated, samurai chopping, temple defending, shuriken flinging, ninja slicing, martial arts fun!!
