Good try!
Considering it was only a test its pretty awesome.
The graphics were only stickmen but the animation wa real smooth. I thought the weapons could have looked better especially the katana.
The sound was ok could have pt some decent music in it though.
Violence. The whole game was about violence but it could have been more gory.
Interactivity was good but the interface could have been spruced up a bit.
Humor. The boss you have to admit is pretty funny.
Overall is was a great try for a test and hopefully you will make a full length version with more detail. Maybe your person could actually walk across the screen rather than stay still. Also you cant actually loose the game.
