Just downloaded and played it for a couple of minutes - great fun.

And if you normally reverse your mouse during a game (no, it's not a metaphor), here is how to do it.
Start up the game.
Press "~" to open the console.
Type "invertmouse" (without the quotes, no space) and press enter.
Press "~" to close the console.
Yay, the y-axis is inverted.
