Speaking with Cubed3 today, Nibris has confirmed a few details people might have been wondering about. Recently there was an announcement that 'The Bloober Team' is working hard on a new WiiWare title called 'Last Flight'. Included in the report, though, was mention of Nibris' two Nintendo DS projects, Double Bloob and ROTR, which caused some confusion.
According to the Polish outfit, The Bloober Team is not working with Nibris and is "right now apart from us". However, the pleasing vertical shooter ROTR and quaint puzzle effort Double Bloob have not actually been sold, despite mixed reports across the Internet. The Bloober Team does have the rights for both games, though, with Nibris focusing solely on Sadness for Wii at the moment.
Finally, if anyone was unsure whether or not Nibris had any involvement in the Last Flight project, then the simple answer was 'No'.
Hopefully that put any recent questions to rest...
