Nacmo Bandai may be working on a Fooly Cooly game for the 3ds.
More details in the link.Hello,
I am currently involved with an action/adventure game based on FLCL (Fooly Cooly) anime for the Wii U. A separate version of the game is being developed by a different team for the 3DS. We started development on both versions of the game in October.
The game will be published by Namco Bandai. Developing for the Wii U has been very painless, and the console's GPU and CPU have made development a very smooth process to create jaw dropping next gen graphics with unbelievable ease. The game's engine was designed to run cel shaded graphics flawlessly at 60 frames per second to imitate the art style and fluid animation of the show.
We have been actively working with most of the old cast of voice actors from the original Japanese show as well as the English dub to return for this game.

I really hope this is true.
