* New doodads: Switches.
* They come in four varieties: wall switch (background element, with
"ON/OFF" text) and three side-profile switches for the floor, left
or right walls.
* On collision with the player, they flip their state from "OFF" to
"ON" or vice versa. If the player walks away and then collides
again, the switch flips again.
* Can be used to open/close Electric Doors when turned on/off. Their
default state is "off"
* If a switch receives a power signal from another linked switch, it
sets its own state to match. So, two "on/off" switches that are
connected to a door AND to each other will both flip on/off when one
of them flips.
* Update the Level Collision logic to support Decoration, Fire and Water
pixel collisions.
* Previously, ALL pixels in the level were acting as though solid.
* Non-solid pixels don't count for collision detection, but their
attributes (fire and water) are collected and returned.
* Updated the MenuScene to support loading a map file in Play Mode
instead of Edit Mode. Updated the title screen menu to add a button
for playing levels instead of editing them.
* Wrote some documentation.

Project: Doodle (Working Title)
Project: Doodle is a drawing-based maze game written in Go.
Features
(Eventually), the high-level, user-facing features for the game are:
- Draw your own levels freehand and then play them like a 2D platformer game.
- In Adventure Mode you can play through a series of official example levels that ship with the game.
- In Edit Mode you can draw a map freehand-style and lay down physical geometry, and mark which lines are solid or which ones behave like fire.
- Drag and drop Doodads like buttons, doors and keys into your level and link them together so that buttons open doors and levers activate devices.
- In Play Mode you can play your level as a 2D platformer game where you collect keys, watch out for enemies, and solve puzzles to get to the exit.
- Easily Share your custom maps with friends.
Mod-friendly
(Eventually) all these features will support custom content in the game:
- Users can create Custom Doodads to extend the game with a scripting language like JavaScript. The sprites and animations are edited in-game in Edit Mode, but the scripting is done in your text editor.
- In Edit Mode you can drag custom doodads into your maps.
- To Share your maps, you can choose to bundle the custom doodads inside your map file itself, so that other players can play the map without needing to install the doodads separately.
- If you receive a map with custom doodads, you can install the doodads into your copy of the game and use them in your own maps.

Built-In Doodads
A brief introduction to the built-in doodads available so far:
- Characters
- Blue Azulian: this is used as the play character for now. If dragged into a level, it doesn't do anything but is affected by gravity.
- Red Azulian: an example mobile mob for now. It walks back and forth, changing directions only when it comes across an obstacle and can't proceed any further.
- Doors and Keys
- Colored Doors: these act like solid barriers until the player or another doodad collects the matching colored key.
- Colored Keys: these are collectable items that allow the player or another doodad to open the door of matching color. Note that inventories are doodad-specific, so other mobs besides the player can steal a key before the player gets it! (For now)
- Electric Door: this mechanical door stays closed and only opens when it receives a power signal from a linked button.
- Trapdoor: this door allows one-way access, but once it's closed behind you, you can't pass through it from that side!
- Buttons
- Button: while pressed by a player or other doodad, the button emits a power signal to any doodad it is linked to. Link a button to an electric door, and the door will open while the button is pressed and close when the button is released.
- Sticky Button: this button will stay pressed once activated and will not release unless it receives a power signal from another linked doodad. For example, one Button that links to a Sticky Button will release the sticky button if pressed.
