That's odd. I havent played yet, and almost looked past precisely because I assumed, if its only a week old and 6 reviews, there's probably not enough content yet. I watched it for later.
So yes, your date being incorrect can affect the chances people will play it. That should get fixed if possible.
Since I've read its like 30% done, I'll give it a try
You should also edit the developers note in the original post, they say " The initial release is roughly a day and a half of gameplay, equating to about 30-45 minutes of play time." and I assume that's no longer accurate. Unless the game is intended to be only a couple hours long.
