The browser version runs great! The inner game is polished and satisfying enough that I want to keep playing run after run. Obviously more depth there would be great to have, but your updates to the outer game horror elements get me the most excited. I'm curious how you're going to use shutting off the game.
Might be too many notes to notice all at once in the beginning, I didn't see the note about shift letting you dash until way later in the game.
Also the open doors didn't seem obvious to me at first, I kinda kept walking around until I got sent to the next room. It could be nice to highlight where to go with an arrow. Once you see it the first time, you recognize the doors after that.
