I think I remember seeing RCE play the demo of this, I thought it looked like great fun and planned to play it when it released :) Then promptly forgot about it >< But its on my wishlist now.
I looked up the video, the game he actually played was a different one called "The Corridor"
I think you and them both came up with a similar concept, Stanley Parable-like narrative game about pushing a button. And both are described as Stanley Parable-Like about a button, so it looks like I probably confused the two games. I'm still going to get it when its done though.
I've actually watched a full playtrough of The Corridor to make sure there aren't similar stuff and I'm pleased to say both games are very very different. For my game The Button is a starting point but it goes in some very weird directions. Currently working on a new level as we speak :D
