Public Demo - Bug fix 4

Howdy, Gainers.

This update to the public demo brings long-anticipated features that should resolve a host of technical issues, particularly for the web and android builds of the game.

What's new?

• Engine upgrade
  • The version of RenPy the Demo is running on has been updated to 7.5. This should fix a ton of issues, including the dreaded "Buffer overflow" bug.
• Android QoL
  • Added a "Hide text" option to the quick menu at the bottom of the screen.
  • Made changes to the visibility overlay so that it displays correctly on mobile.
• Misc bug-fixes
  • Fixed a bug where menu length would sometimes crash the game.
