Today, Gilbert posted a couple of pieces of concept art to his blog, Grumpy Gamer, which is the first hint we've had of what the game will look like. The first one is a lady in a lab coat with outsized glasses straight out of The Far Side (she's called "The Scientist"), and a rough-looking gentleman in a double-breasted suit known as "The Mobster."
This is an idea that has been in my head for a long long long time. It predates Maniac Mansion and Monkey Island. It's a game that needed to be made.
These are two of the playable characters. That's all I can say right now, but more will follow later.
