Hello I've written a clone of the game Laby https://github.com/sgimenez/laby in D.
But it is not complete yet, missing features include :
 - A GUI (it's a simple CLI right now)
 - Accutally parsing any language (it just accepts simple commands)

But writeing it was very delightful.
Roughly 250LOC.
It took maybe 5 hours ... All of it Fun!

git err get it at https://github.com/UplinkCoder/antd

please try it.

> Roughly 250LOC.
Correction dscanner says it's 200 LOC

Currently there is only one Labyrinth hardcoded.
But it's not hard to change, because it's just ASCII-ART
that is parsed.
