Steins;Gate 8-Bit is a purposely retro text adventure game that is a non canon sequel to the Steins;Gate visual novel. It also features references and characters to Chaos;Head another visual novel/anime set in the same universe.
To acquire the actual game legally you'll have to purchase it from one of the various sites that deal in Japanese goods and games like http://www.jbox.com/product/PCG7704 I recommend at least looking at the pictures of its packaging because it had a lot of love put into it.
There's a bit of history between this game and me actually. This was one of the last games I streamed live before I went on a year hiatus and also one of the last streams where I had my stream buddies all together reading dialogue and having fun. We never finished it but because of that I felt like I had to have at least one of my old friends cameo a bit.
