Hi Jon,

Thanks for the code and interest in the Tetris package.  I'd be happy to 
include an Allegro version of the game in the package (I also have a 3D 
OpenGL version that will make it in eventually), but with the code you 
sent, I noticed a couple things:

   - when the game ends, DrScheme hangs, requiring me to manually kill
     DrScheme after each play.

   - once I move left, I always move left, regardless of keyboard input.

I'm using OS X -- maybe this is relevant?
