Ahh, im remember fullscreen was a issue on the Mac, where im used a windowred mode back in the days.
Im do have no longer a Mac. So im have no possible to test it. So its can been some sort here.But its depend if the game actuelly has reach the first code or not or something internal happens. Im have no idea.
Also im completly forgot that little "tank" game. Actuelly like the graphics here.
A bit too much offtypic as its was meant for this game, hihi.
