Thanks very much!
With a real C64 it is joystick only, but if you are using VICE to play then you can just go into emulator options and assign the keys you would like to the joystick directions :)
Thanks for the reply. At the end, the first joystick I tried with VICE (a SNES controller clone), worked. Your game is really nice!!!
Ah, that’s good to hear! Glad you are enjoying it :)
