I'm really tempted! :) This looks fantastic, and I am delighted that there's some storytelling in this game! And most importantly, a save game feature. I'd be playing on a TheC64, so I hope that all works well on it, too. It's basically a stock C64 emulation with somewhat spotty floppy drive support sometimes. Now this game supports more than one firebutton, and Joysticks on TheC64 typically aren't ready for this, so I'm wondering how it'll work then.
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.
