I won't give a rating as I couldn't understand what to do exactly ;/ However making an operating system in a week is a really big achievement :P
From what I understood I should log into User and then I should get access to other commands, tho I don't know where to get pass :P
Also I found the UI a bit unintuitive, like this notepad. It took me some time before I realised how to exit it.
Anyway. That's the game I want to try again as it seems to be really well made :) Good luck!
PS: PLS hint xD
