During my childhood, I never actually owned this game but my best friend did. Sometimes I would go around her house just to play this game as I loved it that much.
I brought this item off Quality-Goods-Online and it arrived promptly and as described (maybe could have added to the description that the cartridge had a name in permenant marker on the back, but otherwise perfect).
The game itself is very simple, the aim of the game is to collect six lost golden coins, there is one coin located in each of the six differently themed zones which normally have three games, a secret game and a boss level. The only challenging zone is Wario's Castle as its the last level but otherwise, this game is easy even to my six year old self.
I would highly recommend both this game and this seller to anyone interested in retro and Mario gaming.
