+Pineapple Pizza
+
+Made for the the Linux Game Jam March 2017
+Requires love2d 0.10 (Super Toast)
+
+A simple game about protecting pizza from yourself
+
+This is a propaganga piece made to show pineapples
+ruin pizza. Don't deny it, you know it to be true
+
+Also, it's in space
+
+The game quits when the pineapple touches a pizza
+as what's the point anymore if pizza has been ruined
+
+Controls : WASD and Space, P to pause and ESC to exit
