Update 1.0.3 (bugs, brightness and Unity-version update)

Heya everyone it's update time! After some feedback and watching a good friend of me play the game (Thank you cocoabatman!) I have come up with this new build. The big update is the port to the new Unity version. I hope this won't break anything.

Other than that I made some things clearer in the game and squashed a couple of bugs.

Log:

- ported to Unity 2021.2.2

        + There seems to be a bug now where the Player can't stop moving in some instances, will investigate.

        + Feel free to DM me if the porting broke anything

- removed two lowest quality settings as they make the game unplayable

- slightly increased some of the music volume

- added faint dustfog for athmosphere

- very slighty increased brightness in some extremely dark areas

- added particles to breaking lamp

- fixed an issue where the guestbook UI wouldn't close when using the close button
