Coil

Coil is a game that was part of The Basement Collection, but I don't know if calling it a "game" is the right word for it.

I find this game extremely hard to write about because the whole thing is so abstract.  Basically, it is a puzzle game where you must follow the growth of this weird alien creature.  Each tasks you with moving a thing or collecting pellets or something, but never actually tells you what it is exactly you have to do or how to control it.  This may seem like awful design, but it's all really simple stuff that you can figure out in about 30 seconds if you have a working brain.

Between each level you get a little text screen that tells some kind of story that may or may not be related to what is happening on screen depending on how you read into it.  Coil is an "art" game through and through, something that you could sit around and discuss the meaning of if you were wearing a striped turtle neck and a beret.

As a game, it's not all that fun.  It's short and you don't actually DO all that much, but if you're into artsy games then you'll get a kick out of it.  Me on the other hand, I prefer my artsy games to have some actual substance to them.
