+## March of the Sinister Bricks
+
+This is a simple game for the (Playdate)[https://play.date] handheld console. In it, you use the crank to control a paddle, and try to break the bricks marching toward you from the right.
+
+This is, of course, a completely novel idea and is dissimilar from any other game ever made.
+
+It was written as part of a series of games to learn the Playdate SDK.
