Interface update and minor fixes

Upon recieving a suggestion about updating the interface on Discord - I did!

What's new?

• Added a Characters Info screen to the game - it contains information about all the characters you've met so far. It updates with  new information sometimes,
• Reworked the Settings menu,
• Fixed typos

I hope you're enjoying playing through the demo ~ 

Don't forget to join the Discord server, the characters info screen was suggested there - if you have any other ideas, I'll be happy to listen to your feedback.
