The best thing is that the idea itself is quite simple but it actually is just a start. You can do much more with it than just linear corridors. Although I want to keep it not too crazy as some ideas I have might induce motion sickness way too much.
I think that I started with ZX font and made it wider. I will be probably changing it a bit. GUI is now "ok enough". Not great but does what it should. Still how the stuff is arranged there etc is more important.
The main menu is temporary as hell. It's the second version, the first one was much worse ;)
