Final update before release

This update is fairly minor. The demo page now comes with a download for a single executable along with an installer if you prefer to simply have the executable itself to play the game rather than installing the program. It's still recommended to install the game to make sure it runs properly, but there should be no issues with the executable either.

• Small addition of the single executable to the game's page
• Small modifications of the introductory lines of the demo's text
• The sequence initiating a puzzle has been slightly modified as well

The full game is scheduled for release on July 27, 2018.
