It seems to be a piece of shit, technically. I couldn't get the game to start. I mean, it starts, and I can move all over the place, but nothing else happens. Nothing attacks me, and I can't shoot with anything I could think of pressing. (Should be the mouse, but I tried lots of keys too. I alt-tabbed out to read some more about it, but it would not let me move the mouse cursor out of the top-left corner on the desktop. So I alt-tabbed back in, and it crashed out with an error.
Edit: Tried it on the other PC. Same behavior. My guess is that the mouse/KB control is broken, maybe because it can't find a joypad. It complains about no recognized joypad in red text. It's also not aspect-ratio aware, so it's squashed-looking too. I think I'll pass until next revision.
