+## Crank-Rotation Object Nudging Game
+
+This is an extremely simple game for the (Playdate)[https://play.date] handheld console. In it, you use the crank to control a paddle, and try to keep the moving Object from reaching the space behind the paddle by Nudging it with the paddle.
+
+This is, of course, a completely novel idea and is dissimilar from any other game ever made.
+
+It was written as an excuse to learn the Playdate SDK, and is made available here in case it serves as a useful tool for basic object-oriented development in Playdate's LUA library.
