I have to be honest, I had never played, seen, or even heard of Q*Bert before you posted this. Although on the other hand the "cubes"(is that what they're meant to be called?) are really nice and the carrot is nice and inventive.
Besides having neither played the game or heard of it, it's a very nice moc.
I just found a version of Q*Bert online and I played a little bit. Now I have to be perfectly frank- I stink
at that game. Oh well, first time for everything...
