I think there must have been something wrong with this. I went to Single Player Mode and I couldn't press anything to beat my enemy. What I do have to admit is that the designs in this game are actually very well done. Some of it looks dated, but definitley fine to look at. I like how there's always a lot going on. Maybe it's changed since the last time everyone reviewed it?
I thought the intro was pretty weird. It just didn't seem to make sense in giving this a story. It still manages to have some pretty creative characters and elements. It does need an update after all this time. I don't know what the "3,5" thing means.
