Hidden Palace, well known for their work recovering Sonic the Hedgehog prototypes, has recently added two prototypes for Klonoa for Project Deluge! One is dated about 19 days before the US retail release, but a couple months after the Japanese original, and as such contains little of note. The other is dated three months before the initial Japanese release, and contains many notable differences, which'll (hopefully) all be documented sooner rather than later. From music and voices, to spritework and control differences, this proto will have many elements that stick out to even those who aren't as familiar with the game as this community likely is!
