I downloaded it again. This time I could run it.

I think the models and maybe the original idea are not too bad. But one could make more of it.
Because, more disturbing than the awful texturing it the complete missing of the lighting.
It makes it uninteresting to play this game.
These advertisments an the walls for god seem a little ill.
Also it is really boring to play it. The music is terrible. (Actually you get sick after two minutes from the midi sound, and the melody)

And the sounds in a game are at least, if not more, important as the looks.
So again: One could make more of it.
