This interview with the three Jumping Flash! 2 teams of MuuMuu, Exact, and Sony was originally featured in The Playstation magazine. In what appears to have been a very congenial development, the teams here discuss character design and their motivation in making JF!2. Overall it's a bit light on info, but consider this an appetizer to the longer JF interview we'll be publishing with Yukihito Morikawa in the near future!
