Retro fans will be pleased to know that Rare's Gregg Mayles has continued uploading behind-the-scenes info relating to Donkey Kong Country. After revealing that Shigeru Miyamoto was the one behind DK's tie, Mayles has offered up some more concept material, including a hand-written document which shows that at one point, the development team considered adding caged animals which had to be releasing by finding keys.
Amusingly, the document features the like "Is this too Zelda(ish)?", which shows just how inspirational Nintendo's output was to the designers at Rare.
As well as this sheet, Mayles has posted up an entire unused level laid out in Post-It notes, a practice which he relied upon heavily during the Donkey Kong Country design process.
