Decided it is about time I got a demo out for you lot to have a play with so above is the complete first level.
Instructions in the readme.txt. If you don't have a decent graphics card, I'd suggest you turn the resolution down to 640x480 in the main menu. I've had success running the game on computers with built-in SiS cards like that.
If you get any strange artifacts on the screen, make sure you are not forcing anti-aliasing or ansiotropic filtering. [EDIT] You also need to ensure that your card is not set to force vsync off, although this is something I am working on.
Enjoy, come back and comment. There is no FireStar pick up on this level, so you'll have to wait until the next demo to play with that.
Also, just because I like you, rate++
