nothing wrong with that, as long as it doesn't get too dark. Twilight Princess, for example, was one of Zeldas two darkest games, (the other being Majoras Mask, which was awesome) and it's the best game ever!
and TTYD, the darkest game in the paper mario series, (spm was dark, but even Mimi and Dimentio couldn't make as dark as ttyd), was the one of the best.
so nice to meet you... and your mustache!
you know, it never shows Dimentios face... just an Opera mask covering his face.
EDIT: we need to get more people to post here.
