# Changes

## v0.0.10-alpha

New features:

* Added the **Eraser Tool** and support for **brush sizes**. Now you can clean
  up your mistakes and draw shapes with thicker lines!
* Added the **Ellipse Tool** for drawing elliptical shapes.
* Added a third example to the game's built-in levels.

Bug fixes:

* The Undo command now restores the original color of a pixel instead of just
  deleting it. Only works for thin lines so far.
* Improved collision detection algorithm to prevent players from clipping
  through a solid doodad, regardless of speed. This change is invisible this
  build, but opens the door to improvements in the 2D platforming physics and
  making the player character move and fall faster.
* Fix mobile non-player doodads from sometimes being able to clip through a
  solid doodad. For example, a Red Azulian could sometimes walk through a locked
  door without interacting with it.
* Sometimes hitting Undo would leave a broken "chunk" in your level, if the
  Undo operation deleted all pixels in that chunk. The broken chunk would show
  as a solid black square (non-solid) in the level. This has been fixed: empty
  chunks are now culled when the last pixel is deleted and existing level files
  will be repaired on next save.

## v0.0.9-alpha

First alpha release.
