I just finished the NES version of this game and it's actually pretty good.
In most respects identical to the Spectrum version other than different graphics and sound. And a few gameplay differences which made it interesting to play even though I finished the Spectrum version a few days ago.
And I managed to find all the coins in this game without any hints, they're much easier to find. Looking for them is actually kinda fun in this one as getting them sometimes involves a puzzle.
What do you people think of this version?
