Over at Desura, indie developer MZ1 has released Wake Up Call, a short (15- to 20-minute-long), surreal story that takes place within a comatose man's mind.

Wake Up Call consists of several brief gameplay snippets that represent the main character's attempts to retain control of his own inner logic and spatial reasoning. As gameplay progresses, the man will eventually recover his lost memories. I like the concept here -- the word association scene is particularly interesting.

Wake Up Call is available as a free download for Windows, Mac, and Linux.
