Cover and QOL update

Hey everyone,

I implemented some QOL in the demo: you can now press escape to close most windows (tutorial, inventory, etc).

Also, new cover art! Let me know what you think.

The main game is advancing at a good pace. I'm preparing a stable version for an EA release which should be near the end of this year, if all goes well.
