Sounds good mano, that you rewriting the game and also, that you want to improve graphics and some other things. Looking forward to this new version.
The Poke you mentioned, you could write it here on the side. Maybe also other players of "Serpland" want to change Level3 to normal-speed? Or, i think this would be even better, you change this thing in the game and then release it as v1.1 here. Then even some C64-beginners, don't have to be afraid, that they can't manage this thing with the Poke themselves.
Best regards.
