Demo impressions:
Great work on PC visual enhancing.
Great work on PC controls. Apparently you can also control the camera placement with a set of keys, which is a welcomed feature by everyone, i bet.
Good work on Gamepad controls, but the launcher configurer was buggy under Vista( Server 2008 x64, to be exact ), making the mouse go crazy, and the control schemes available there are absolutely confusing. Other than that, configuring the gamepad inside the game works perfectly fine, although you're a bit limited if you're using a PS2 like gamepad, like, for example, mine, a Speedlink ThunderStrike.
I encountered some problems when playing the game that resulted in giving me an error too, but not too often and i suspect my Windows XP SP3 installation may very well be the cause of it. The rest of you who can't run the game, you might either have a hardware issue ( a non SSE2 CPU, like an old Pentium 3 perhaps, or a graphics card that lacks Shader Model 2, or 3, i forgot which one is required as a minimum. It can also be that your windows installation is messed up by spyware/viruses or some other software.
The demo is playable on just about any computer out there that have the required hardware capabilities ( Shader model, a more recent CPU that supports SSE2 instructions at a minimum ), because you can literally go to 640x480 resolution, and as blocky as it is, the gameplay will make you forget about it, and you can still enjoy the game.
I will be posting a video soon, on Youtube and possibly as a regular download aswell, as soon as i can beat the demo in 10 minutes and with Turbo mode.
