Can't wait for the full version
If this was at all possible, make the full version of the game downloadable. That would be so awesome...
As for the demo itself, it was very well made.
Graphics were finely tuned with the game, adding to the style of the game.
As for the sound, I loved the music.
For violence, there wasn't much, but enough to keep the demo interesting.
For interactivity, it's a game- duh.
For humor, I chuckled when I saw that Shadow was getting addicted to trading cards.
Overall- 10
As said before, I can't wait for this game to come out. As long as you keep this style, and add variey, it could easily make the top 50, as well as gather a large fanbase.
