I have check in amiga forever because i dont have time to try in a real amiga and seems to work with right ctrl and keyboard arrows, let me know if it works for you.In practice i have made anoter try and works only space bar i think in a real amiga? i dont know if there is a combination of keys to make it works, the other developers says that is very hard to change controls in scorpion engine, so can you buy a joystick only for a demo? Or it will be useful also for other games let you see! Have a nice day!
