We haven't heard from Retro Studios in quite some time. Outside of their work on Donkey Kong Country: Tropical Freeze's Switch port, the company has been absolutely silent. Could there be some big trouble brewing at the studio? According to one former developer, that's indeed the case.
A former employee of Retro left an extremely negative reveiw of the company on job site Glassdoor. In the post, he talks about studio mismanagement and other issues. He also makes mention of half the employees expecting Nintendo to shut down the studio any day now.
There's no chance in hell Nintendo will comment on this with any meaningful details, so I guess we'll just have to cross our fingers and hope that things turn around for Retro.
