 # Changes
 
+## v0.1.0-alpha
+
+New doodads:
+
+* Start Flag: drag this into your level to set where the player character will
+  spawn. There should only be one per level.
+* Crumbly Floor: a rocky floor that breaks and falls away after a couple
+  seconds when the player (or other mobile doodad) walks onto it.
+* State Blocks: blue and orange blocks that toggle between solid and passable
+  when the corresponding ON/OFF button is touched.
+
+New features:
+
+* An inventory overlay now appears in Play Mode when the player character picks
+  up one of the colored keys.
+* While editing a level, you can click the new "Options" button in the top menu
+  to open the level settings window (like the one you see when creating a new
+  level): to change the wallpaper image or the page type.
+
+Other changes:
+
+* Added better platforming physics to the player character: acceleration and
+  friction when walking.
+* The colored Locked Door doodads have been re-designed to be shown in a
+  side-view perspective and have an open and closed state in either direction.
+* Tooltips added to various buttons in the Editor to show names of doodads and
+  functions of various buttons.

+## Cheat Codes
 
-* In an **Unbounded** map, the game will sometimes spaz out in Play Mode when
-  the character moves into negative coordinates (off the top or left edge of
-  the level). Stick with only "Bounded" and "No Negative Space" levels instead.
+The following cheats can be entered into the developer console.
+
+Play Mode:
+
+* `import antigravity`
+  - This disables the effects of gravity for the player
+    character. Arrow keys can freely move the player in any direction.
+* `ghost mode`
+  - This disables collision detection for the player character
+    so that you can pass through walls and solid doodads. Combine with
+    antigravity or else you'll fall to the bottom of the map!
+* `give all keys`
+  - Adds all four colored keys to the player's inventory.
+* `drop all items`
+  - Clears the player's inventory of all items.
+
+Experimental:
+
+* `unleash the beast`
+  - Removes the 60 FPS frame rate lock, allowing the game to run as quickly
+    as your hardware permits.
+* `don't edit and drive`
+  - Allows editing the level _while_ you're playing it: you can click and drag
+    new pixels with the freehand pencil tool.
+* `scroll scroll scroll your boat`
+  - Enables Editor Mode scrolling (with the arrow keys) while playing a level.
+    The player character must always remain on screen though so you can't
+    scroll too far away.
