The fabulous C64 version of course. Nice front-end, good in-game graphics and the great music. Good stuff, probably the best of the Dizzy spin-off games I think.
Well the 16bit games just look soooo much nicer... However I'll have to go with the Commodore version as it's the version I grew up with and for an 8bit game it looked nice, played well and the music was great.
