Just an art update

Not really much to say at the moment, but I just spent a lot of today updating the menu graphics and cleaning up the levels for the demo. Still a lot of "work in progress" art that can be polished up later on, but working on trying to give the game some kind of cohesion? I dunno.

I did style the help and options menu in a vaporwave style but I might change that later. :P
