played it, love it. fantastic work on that new installment, two! =D
the sledgebrothers are a cool addition, really love'em, one question though. is it possible to integrate a sledge fight into world mode? it would make an epic ending =D
the game runs pretty smoothly, no errors detected so far. the inclusion of the AFE-sledgebros kinda made me think. why not include the code-items from that one into the game? The boomerang, giant sledge hammer, smb2 fire and the triple hammer shot were all fun-to-use weapons in SMW.
love that "your map has been saved" message in the leveleditor btw =P
i actually might try to make some maps for the beta 2 release, if that's ok with you
EDIT: Love shy guy tag mode
