Changes and additions:

• Grouped sprites into specific texture groups to increase performance.
• Made mushroom bugs that move up and down on the side of walls in addition to the mushroom bugs that were already moving side to side on the tops and bottoms of walls. Reworked some of the sprites for the mushroom bugs.
• Added pink mushroom sprites for the mushroom bonus area.
• Replace all the instances of the foreground tiles that used one of the old tile sheets with tiles from the new tile sheets (no cosmetic changes here, just getting thing to a place where unnecessary assets can be removed from the game to help with performance optimization).
• Made the autotiling script slightly faster. Loading into the overworld should be slightly faster. Loading some levels that have objects which autotile when loading the level should be slightly faster.
• Reworked the 'new record' sprite.
• The black slime sprite that shows after beating a boss now has more detail.

Bug fixes:

• Fixed issue with steam overlay leaving artifacts on the black bars that appear if the game window is a different aspect ratio than the game camera.
• Fixed bug where the sidebar would retain its current opacity even after the player doesn't exist any more (such as when the player dies or in instant replays).
• Fixed bonus walls incorrectly tiling with normal walls.
• Blocker ghosts now work with the colorblind options.
• Fixed misaligned sprite for the right-facing red button.
• Fixed issue with the death splat not work properly on buttons that are depressed.
• Fixed issue with buttons sometimes not triggering when quickly jumping on/off.
