1 XEmeraldia, Drop the blocks. If you drop a square on top of one of the
2 same color, they (as well as any neighboring blocks of the same color)
3 will both be shaken by an "impact". The first impact will cause fractures;
4 the second will cause the block(s) to dissolve.
6 You can either use the arrow keys or vi-style (hjkl) keys to move/
7 rotate the blocks. `s' or `p' will pause the game, and if your boss
8 comes along, `q' can be used to avoid an unpleasant confrontation.
