Comment what you'd like to see in Vault 1.1! This could be:

• Bugs that should be fixed
• Features that could be added
• Environments that could be explored
• Characters you could encounter
• New gameplay modes
• ...Or anything else you think of!

I don't have any specific recommendations. Interacting with operating systems always freaks me out a little bit. But a couple games that I think break the fourth wall well are The Stanley Parable and OneShot.

Maybe you could get some inspiration there?
