it is the beggining
this could be big. it is a new type of game. you are just running and try to avoid things and no game is like this. here is what you should add:
*checkpoints i hated starting over.
*possibly weapons maybe not.
*better graphics for moving and blood
*more characters though i didnt finish game i figured that there are no more characters throughout the game.
good luck with the project i will be watching for it!
