I really liked the graphics and the sound of this game. However, for me it was not really clear what I need to do. I wished there was a more detailed description of what the purpose of the game is and what the red and blue sword does. I figured it out after a while, but I think it would be good to just add a short description.
I think this is a nice start for a game, but might need some additional work to add a bit more diverse gameplay.
Congratulations to your entry!
