Hm, it must have been either Buggy Boy, or Xenon 2, or Lotus (2). Twas not my A500 though. (never had one 'till 1997)
Graphics didn't blew me away, we had a 386 at home with vga (1988) though lots of pc games had ugly cga gfx, but all the a500 versions had neat 'vga' gfx. The thing that blew me away was the sound (especially of Xenon 2).
