DONT JOIN... (read description)

I found this game while freeing up some space on my laptop. I have no idea how it got there or who made it. I played around with it for a little while, and it’s just some silly text trying to convince me to leave the game for some reason. (Edit) This game also came with a weird description. I have no idea what it means, but I’m not going to delete it—it’s probably important. Delta Oscar November Tango Tango Yankee Papa Echo Sierra Echo Charlie Romeo Echo Tango.
