Demo release and various updates

We've rolled out our demo, and the turnout has been incredibly gratifying! Thank you everyone who's tried it out, it's been a blast seeing Let's Plays pop up on Youtube and Twitch alike.

A new patch has been deployed in the interim, thanks in part to the community's feedback, bug reports and ideas:

1. Improved Bob and Susan's pathfinding to reduce incidences of them fighting over the same doorway.
2. Fixed a bug during the tutorial where skipping steps could softlock it.
3. Moved some tutorial indicators for better clarity
4. Clicking the smaller icons for the NPCs on the whiteboard to select them will now satisfy the "Select an NPC" step of the tutorial (previously it was only the larger portraits).
5. Added more rescue-able cats to the Lobby.
6. Changed the spirit box slightly to better signal that the voices from it are spirit box evidence, now accompanied by short static sounds.
7. Prevent spirit box evidence being given before the mission starts.
8. We now remind players to start the mission if they try to give orders to Bob and/or Susan before the door has been opened, to avoid confusion.
9. Adjusted some place item locations to avoid cases where things could be placed under the floor or too high.
10. Added an auth flow to the Twitch integration that vastly simplifies it for the user (now at the click of a button).
11. Fixed the scroll wheel for the microphone input dropdown.
12. The ghost no longer automatically opens doors when moving through them, but has a small chance to.
13. Added additional NPC reactivity.
14. Added more spooks (you'll have to find out for yourself).
15. Removed Chuckles.
