This was just awesome. The visuals are great and makes it feel authentic. The messages in the console fits the style of the game really well, and the console commands work great.
Maybe a bit more audio would have been cool.
At first I was a bit confused about the coordinates because the x and y are switched around. Don't know if that is intentional to make it harder. Anyway, I started to think of it as two-dimensional arrays, to avoid having to toggle all the time. That helped.
If you should decide to develop this further, I would definitely come back for more. Great game!
