looks ok. I would upload your pics to imageshack then copy the "direct link" to to ware the null is in the image thing
ex: [img]your direct link [img]
if that made any sens at all.
SLOW DOWN, it looks rushed like others have side. also like otheres have said add some light maping and more entitys. If your having a demo i would make a storyline for the game, how in the world would anyone know wy theres a telephone in the cave?
i think this game could have a chance if you did the flowing:
1. add a storyline
2. add light maps
3. add more entitys
4. work slow and make everything make sens were it is
