Well, I have a game that I did start back in June, but since using this jam to finish other projects is okay in the rules I figure I'll submit it here. I didn't get very far with it, and I desperately need an outside force setting a due date or else it won't get finished. ^^;
Its a mystery/sci-fi visual novel about a robot trying to solve a mystery on a high-tech cruise ship. The player takes on the role of his human assistant. The story does change based on player choice: there's four different possible culprits depending on player choice, and the robot detective will change his style to balance yours (if you're aggressive, he'll be gentle, and vice versa). All of my robots are object-headed: the detective has a camera lens, a waiter has a tv head, and a lifeguard has a blow dryer head. The whole thing is based on a couple of really surreal dreams that I had.
