Oh wow I've never heard about this one before. Could I get more details on where and when this happened? Right now, I have no clue myself on what's going on haha
I think you got it confused. I simply post updates on the game's progress in my Discord server -there's no secret new build there. As soon as I have the new demo version ready, I will be updating the demo here as well as launching a Steam page.
Regarding the coins, the tip is to find the "wobbly" props. But if you just want to know where they are, then: Left chair in the lobby, the toilet, and the plant in the elevator button room.
