Coming to us from New Zealand and due for release on PC, Mac and Linux in March 2016, Mogwash is a retro mashup of Wonder Boy and Rainbow Island, also inspired by PC Shareware games like Duke Nukem and Commander Keen. (Due to the country of origin, I kind of expected The New Zealand Story to be part of the inspiration too! :-D) Looks uber-cute and very retro. Check out the Greenlight page.
