Quality-of-life update

And here's the PC patch! As with the update to the VR version last week, this is just a minor quality-of-life patch to the game. I wanted to close out a few nags before I consider this project wrapped and go into full production of the next game.

Same as the VR version, the biggest change is that I FINALLY got a reset function to work. Now you can jump from the ending back into the puzzle room without having to restart the entire puzzle again. Sorry to everyone who ground out the endings before this was available.

Other changes in this release:

- Added a Windowed mode
- Added a "Dark Mode" on the end to change the background for easier viewing for some users.
- Reducing the brightness of the white end background.
- Fixed the walk animations to look more realistic.
- Fixed the blue and green gem physics so they don't float in the air when you release them
- Fixing a bug where dialogue lines would sometimes overlap
