serioiusly give it a chance, me and a mate got stuck on one of the early levels and it was infuriating but when you get passed that it's fun until Advanced 29 (i think) that is an exercise in pure madness!!! It's an amazing multiplayer game tho! Give it another go.
I've heard that SMB2 will be better value in that you get all the games (monkey target, fight, race and the like) to start with and then go on to unlock even more.
Level 30 on Advanced in SMB1.....
Don't even think of trying to tip-toe over to the gate, all those revolving platforms are just way to difficult......
Steam straight over the platforms when they align, it's the easiest way
