The level editor is nearly complete! There's only one more feature left that I want to implement (being able to select multiple instances and move them around). I'm super happy to introduce an undo/redo system to the level editor in this update! This is something I've wanted for a long time, but because of the way instances in the level editor work, it's been quite the task to get the undo/redo system fully working. I also managed to find a bunch of small bugs and squash them in this update :)

Level Editor Improvements:

• Added undo/redo system to the level editor. Note: playtesting a level resets the undo/redo history.
• Added "New" button for creating a new blank level without having to exit and re-enter the level editor.
• If trying to create a new level or load a level and there are unsaved changes, the level editor now warns the user.
• Information display now has a transparent black background to make the information text easier to read.

General Changes and Additions:

• Quick play now displays "New Record" if you beat your previous fastest time.
• Quick play now displays the player's fastest time in the upper left.
• The upper left times bar now displays sub-second times in milliseconds (rather than as decimals).
• Removed background parallax effect in the level editor edit mode.
• Added pink crystal laser that rotates counter clockwise.
• Added fading transitions between the menu and the level editor, quick play, and story mode.
• Snowballs now explode when hitting player.

Bug Fixes:

• Fixed bug where beating a boss would crash the game. This was caused by the game trying to reference levels files that had been removed in one of the latest patches.
• Fixed issue with game not being able to accept input from non-Xbox controllers.
• Darts are now destroyed when off screen so they don't clip through walls.
• Fixed issue with moving the music slider. The music controller was not tracking the change in music volume properly, and moving the sliders too fast could cause the music volume to not be updated at all.
• Fixed issue with extender blocks being able to clip through offscreen walls. Now extender blocks only extend if they end point of the extension is within the active view area.
• Removed collectible goo from level editor objects. It was accidentally added to the goo object section of the level editor objects in one of the latest updates.
• Cutscene volume no longer automatically maxes out (it stays at the music and sound volumes the user had set). This also fixes the issue with the volumes not getting reset properly after cutscenes.
• Fixed issue where pressing the keyboard button to toggle the level editor information made the grid button light up instead of the information button.
• Fixed issue with lasers not stopping at ice blocks (if the ice block is outside of the view at the start of the room).
• Fixed issue with the menu selected button history not updating when going into quick play or level editor (meaning when you come back out of the quick play or level editor areas, the selected button would be on story mode).
• Fixed bug where the global stage name wouldn't get updated when going into the level editor, so if the player went into a level in Story Mode, that level name would carry through to the level editor. This caused the in level doors to have goo on them if the player had beaten that level.
• Fixed bug in tutorial area for the white slime player dust. The dust sprite was be green (instead of white) for both the white slime and the green slime.
• Fixed a few small memory leaks.

Known Bugs:

• When screen is stretched by a non-integer multiple, tiles can draw parts of neighboring tiles. See this GameMaker: Studio documentation page for more information: https://docs.yoyogames.com/source/dadiospice/001_advanced%20use/more%20about%20backgrounds/designing%20tiles.html
• When holding a sidebar slider and the screen shakes, the slider moves.
