At this point, I think it’s a safe assumption that the game is never going to be released on Steam willingly. Some people I’ve spoken to believe that the stream cut off where it did because the game is nonfunctional past that point, since while it may be a game that relies heavily on story Let’s Plays of it have been on YouTube for years by now. And what you saw in the stream is what you would be getting, because there are going to be no patches if Amanda isn’t there to fix things. A few people with way too much curiosity and time did a little digging into Brianna’s past and checked up on her credentials for things like software development and engineering…and found that at best, the stated credentials were outright fabrications. And based on the tweets observed when Brianna was recently building her VR capable computer, outside of using Twitter Brianna lacks the knowledge that anyone who took CS101 in the past two decades would be aware of. Sorry to say it, but you’re probably not going to be getting what you paid for.
Also, whatever Brianna uploaded to Steam hasn’t been modified in over two months. Marketing/promotional material likely hasn’t had any progress whatsoever.
