Coder's block

In this game, you push a block (represented with '#') around a map, attempting to avoid falling into pits, opening gates (red squares) by pushing down switches (red 'o's), etc.  You can also recover blocks from pits, in case they have fallen in--but be careful: that's the *only* situation in which you can recover a block.  Get to the green '*' and you move on to the next level, or win!
