There's a separate startup script for Linux, which invokes Wine (needs to have been installed) to run the emulator.

This game utilizes the same basic controls as Steel Ranger and is possible to play using a 1-button joystick without touching the keys - doubleclick fire to access the inventory / weapon selection. The possibility for extra buttons is a convenience - e.g. using an extra button to jump instead of the Up direction.

It is slightly over 800 screens, and should be a longer experience than Hessian, though the exact length depends on the playing style.
