I dig the look of the terminal, and the idea. It fits into the theme in a subtle way that I really like. Short but sweet.
About the only easter egg I could find was [spoiler] the name of the jam.
There’s a couple of spelling and grammar mistakes, like ‘you don’t are login’ instead of ‘you’re not logged in’ (I don’t hold it against the game, I just think you might want to know.)
