+summary: The unquestionably awesome 2D game engine
+description: |
+    LÖVE was created to be a user-friendly engine in which simple (or
+    complicated) games could be made without having extensive knowledge
+    of system or graphics functions and without having to dedicate time
+    towards developing the same engine features time and time again.
+
+    Developed with cross-platform implementation in mind, it utilizes the
+    latest open source libraries to deliver a similar game experience,
+    independent of operating system. By relying on the Lua scripting language
+    for game-specific programming, it allows even the novice game creator to
+    quickly and efficiently develop an idea into a fully working game.
