Are there any companies that could be interested, that would be able to release it in Europe and Australia as as well as North America? If so, I'd be glad to help out.
Even though I couldn't see a Chirari page anywhere on the Japanese PlayStation site, I decided to try viewing the page for its game ID to see if it exists, and it does
! Maybe I wasn't looking hard enough before.
Anyway, two of the screenshots they have are of the profile screen, and while we knew from the worldwide announcement that there are now 60 stages, according to the screenshots there are now 70 doors - also an addition of 10 from Sayonara, suggesting none of the new stages have multiple doors - and five more backpacks bringing the total to 45.
Something that caught my eye, though, is that they mention Kiyoshi Sakai being the programmer of something called "The Mosquito". The first thing that came to mind was Mister Mosquito (Mr. Moskeeto in PAL regions), which was simply called "Mosquito" in Japan ("蚊"), but after watching the credits for that game, I didn't see his name anywhere. Not really sure what the deal is there.
That's got me stumped. I had a look at the credits for Ka 2: Let's Go Hawaii - although you might have seen those credits too - but his name isn't there either, and I can't find any other game it could be referring to.
