SMS was a very good game, with the very neat idea of playing with a water gun. Sound, graphics and story is very tight. However all the levels that you play without the water gun, are extremely frustrating and really badly made. Because of bad cameras, unresponsive jumping...and so many cheap deaths. The other levels are all very well designed tho. Some of the jumping techniques/shemes are a bit frustrating, and sometimes feels completely aleatory. It's worth playing but required a lot of patience if you want to finish it. I do not think it's a good game for children, too much complex levels at times, and problems of control and camera. That said it's a very good Mario, and the only one i fully completed, with Mario 2 on SNES.
