i have tried to finish it and played it for a fair amount of time but got board and give up, i didn't like the slow game play and the music playing bits they seem to interrupt the flow of the game. its shame as i love the wonderboy games.
I went on to play last game they did on the megadrive Wonderboy 6 (MonsterWorld 4) realy enjoyed it, looks and plays really well, the little cute creature you get to throw around makes the game diffrent. but the last dungeon is setup to piss you off and make the game longer that's the only down point.
