Given the game length and pedigree of the developer it's no big shock that the Donkey Kong Country challenge has been extended to part 2. There will however be no more extensions as Arino tries to topple the evil King K. Rool.
In the latest Project: Game Version 2 update we get to see a new feature inspired by Arino's behaviour on the show. Plus the last game of the collection is revealed to be 16-bit inspired.
