+Libraries included are:
+
+* [AnimatedSprite](https://github.com/Whitebrim/AnimatedSprite): Used for the player
+* [pdParticles](https://github.com/PossiblyAxolotl/pdParticles): Used for walking pdParticles
+* [Playout](https://github.com/potch/playout) - Used for the information popups in the Stats scene
+* [Signal](https://github.com/DidierMalenfant/Signal) - Used to notify the scene when an item is collected
+
+## Notes
+
+* I've created a [base scene](source/scenes/BaseScene.lua) with a some default behavior that makes it easier to interact with the system menu
+* The [play scene](source/scenes/Play.lua) uses sprites for the world, and most of the input is handled by the [Player](source/scripts/Player.lua) class
+* The [stats scene](source/scenes/Stats.lua) draws the grid in the background so it always shows up behind sprites
