Ok I've missed out on the Wonder Boy games aka the Monster World series and actually purchased the Wonder Boy the Dragon's Trap (XB1) and last month games with gold gave me Sega Vintage Collection Monster World and this game Monster Boy in the Cursed Kingdom got pushed back well the title sounds similar but not quite the same and the article at Trueachievements.com said this game is related to the series.

Digging on Wikipedia SEGA owns the rights to Wonder Boy but they apparently have nothing to do with this although the same developers are behind the game based on game which needed a name change something something about booze in the title. while I was not sure before i'll try to keep an eye on this one.
