Hey, all you blockheads out there, Gamasutra has a nice postmortem feature from the creator of The Blockheads. All blockheads can read what David Frampton has to say about the creation process of the game, including what went right with the development process and what went wrong.
"Minecraft did influence the art in The Blockheads. I didn't directly copy it, and in fact I resisted the urge to ever look at Minecraft's art directly for inspiration, always coming up with my own idea of how things should look. However what I did take from Minecraft was the rather specific solution of real-life inspired low resolution pixel art on cubes."
