Version 3.0.6 - very minor changes

Just a very minor update to fix a few things I've found over the last few weeks.

Version 3.0.6:
- Fixed screenshake option not working at all.
- Fixed cutscene gallery being always unlocked.
-- (should only unlock after beating the game)
- Fixed broken bandcamp link.
- Added links to Twitter and YouTube.
- Coffee price halved to 500.
