Fun, but...
It WAS a fun game. I played all the way through. But I hope that this grade wasn't for science or english, because you would have failed miserably. To start, Pluto isn't red. it is not next to Mercury either.And speaking of Pluto, I'm pretty sure it was denounced to a dwarf planet before you made this. But you might have just uploaded it a long time after making it.
As for the other thing, the story was just dumb and the grammar was not awesome.
