I bought this Kafkaesque game back in 1996 and played and enjoyed it quite a bit it quite a bit even after finishing it the first time: In this a game, you play as the protaganist after having turned into an American cockroach (after an attempt at black magic based on greed gone bad) roaming around presumably trying to figure out how to turn back, though the game doesn't explicitly make clear quite what is going on. The extent of your abilities as the roach are to move up, down, left, and right, and interact with things by pushing them or using your weight or presence. The short term goals the roach needs to achieve (puzzles) are cryptically given in the form of poetic (rhyming) riddles that are often subtlely humorous; the puzzles themselves are quite challenging, possibly to the point of being frustrating for some players depending on their tolerence for or enjoyment of adventure game puzzles.
The developers and creaters of the game did a very good job in realizing a very dark and ominous game in tone, atmosphere, and mood. The music is also very good and fits perfectly. The Steam release also includes some extra content: the soundtrack (two compact discs worth) in mp3 and FLAC format, some videos with developer commentary, concept art, storyboards and more.
