This game was at the house of my 12 year old girlfriend (I was also 12) , I think her brother owned it. Since I spent a lot of time around her house this game was played fairly often - maybe in an attempt to impress her. I think we even played this game together... you can see expecting my girlfriends to play computer games with me started from a young age.
This game is one of the best 2 player games for the Sega Master System, there isn't much to say about it. The difficulty is quite challenging however, I don't think I have ever beaten it on the original console. As a single player game it doesn't quite stack up quite so well, but with two players cooperating it is near the top of game experiences on the SMS.
Originally an arcade game, this port of it is relatively faithful graphics wise. The controls are similar and sound is also pretty good. All in all this should be on your SMS want list if you don't have it already.
