According to Patti, incorporating touch controls did not feel like the right move for the game; instead, the developers chose to recreate the original title's experience and market the game to new players.
"We're not using any touch. We didn't feel it would suit Limbo at all," he explained. "It would feel like a patch if we did it. And we really like the original experience. The Vita allows you to have the original experience.
"It would require a lot from us to rethink the game. We would probably make another game if we were going to do that. Vita was a no-brainer because we could keep the same experience. It has all of these great features, but we didn't have to use them."
The game was previously ported to PC where, according to Patti, the studio "put a lot of effort into making the keyboard work. It wasn't straight. It took months and months of testing and trying out. We did a lot of QA around keyboard controls.
"It's the same with the Vita. It needs to be perfect for that screen. There are some things that are different for when the screen is smaller we do to make it work better."
Limbo on PS Vita was announced last night during GDC. The game is in development by LittleBigPlanet PS Vita studio Double Eleven in collaboration with Playdead. It is scheduled to release this year.
