Thanks a lot. High score right now is saved in ram, so you have to use emulator and save ram state. I will think about a saving procedure to disk in 1.0.6.
As for all the other comments and suggestions, I’ll definitely take them into consideration for Ruote Fumanti 2 (I’m already starting to think about), which will depart more noticeably from the arcade version, while retaining the core gameplay mechanics.
