Updated the game to version 0.2.9

Next Fest tomorrow! Tiny update ahead of that.

• Fixed a bug where using some items would turn off the center reticle until you opened and closed the inventory screen again
• Couple other tiny bug fixes
• The usual small tweaks
• Surgical robot has head-tracking when it sees you now, though it’s barely noticeable, it still turns to look where he's going around corners.
• Demo end screen now says the full game is coming soon, which it is. It’s like 99% done, but that last 1% is being a huge pain
