Yesterday Atlus posted a video encouraging people to use their site to tweet in order to unlock an 8-bit version of Odin Sphere. This version is based on the Famicom’s capabilities and would be playable in-browser (details translated by way of Gematsu).
The campaign’s site includes a tweet button that will allow you to support the goal of 28,888. Currently the counter is at 23,858, and the campaign lasts until November 30, 2015. You can see the video showing off what it will look like below.
