Actually I found out a few weeks ago but forgot to post it here.
For those who don’t remember, Oink Games is the mysterious co-developer who turned up in the credits of Chibi-Robo: Photo Finder. Well I contacted them on Twitter for more info and they were nice enough to reply. It turns out some of the staff were formerly programmer at Skip and previously worked on the bitGenerations and ArtStyle series, including Orbient, Aquario, Boxlife and PentaTentacles.
So that’s pretty cool! Anyone who’s kept an eye on Skip’s infrequently updated site will have noticed that their in-house staff have certainly dwindled over the past few years but it’s cool that Skip can contract them back in on a project-by-project basis. So there’s hope for another game with the size and scope of Captain Rainbow again… Right?
