Professor Frank

This is a very large, spare game entered into IFComp. You wander around a large variety of areas, including a library, a secret lab, a castle, and a haunted pyramid.

Gameplay consists of three main mechanics: finding gold rings in odd places, finding keys and later unlocking things, and giving a variety of appropriate ethnic foods to crazed individuals who generally jump out of cabinets, boxes, coffins, and so on. You also have a pirate bird companion whom you can talk to, and a large number of NPCs who lampshade the games incompleteness by saying things like "I would have more powers if I had been implemented correctly!"

Room descriptions are spare, and gameplay can get repetitive.
