Thanks for the feedback - there isn't much to do yet beyond that, mostly the room / atmosphere / visual look is what we have built thus far. I just added the controls to the game page, I overlooked doing that before my bad. WASD for movement, CTRL to crouch (not really much purpose for this right now), E to interact, and ENTER to proceed on the PC.
I hope the linux build functioned properly - this is the first build I've done that included more than WebGL or Windows, and I was not able to test it.
