If at first you don't reach space, try try again..and again..and again..and again..and again..and again..and again..and again...and again...and again....and again.....and again....and again....OH MY GOD I REACHED SPACE! Oh shi- Wtf, there's another part of this game? NOW I HAVE TO REACH MARS? *facepalm* fml.
First thought: WTF A SEQUEL. Second thought: Tutorials that you're forced to take? WTF Third thought: I died on the tutorial you're supposed to take. Fourth thought: When Bowser or "Wart" capture mario's buddies, They don't hang the cage in front of the pipes. DUR.
I'm not one to complain about Mario BUT COME ON! First: Get new music. Star music is from N64, The game music is N64 intro with a mix of NES Mario. Second: I'm known to run around and break bricks in mario. You can't break bricks. What the heck? And getting all coins to make the star re-appear? I find that sad. Third: Luigi? Where's Peach?
This game teaches a life lesson as explained in other comments. You can't rate it more then at least a 4. And even if you don't understand, Ask somebody before you rate it.
