good point about the files, we have a list of synonyms that work for all commands in the code but read isnt one of them unfortunately, for reading files we have:
"open", "cat", "execute", "view", "run"
I did also think about the reticle being hidden but we had so much more important stuff we had to do first that it never got done, we also had realistic keystroke sounds at first but they were replaced. I'm glad you liked the game and i cant wait to try yours out!
