Quality of life additions for Meat Grinder:
- Turn off checkpoints in settings/gameplay to grind a perfect run easier
- Death on first chunk now resets timer, pacifiersand deaths

- Meat Grinder contains two new game modes: “The Daily Grind” and “Quick Play”
- "The Daily Grind" is a randomly generated level that switches out daily. Get to the end as quickly as possible to top the leaderboards. Try as many times as you like! Get better!
- "Quick Play" allows you to play a level generated from all of the "level chunks" in a chapter. Maybe you'll see something new!
- Added "Forever Forge" which showcases the best user generated levels. For now enjoy a Team Meat official chapter called “Abattoir” which is….quite difficult.
- Fixed an issue with leaderboards not filtering scores correctly
- Fixed an issue with text rendering in leaderboards
- par adjustment in 3-1

- Little Fixes

-Fixed an issue with level restarting putting the player in a death loop
-A background image replaces the black bars outside of the 16:9 play area to fill screens with larger aspect ratios
-Fixed level generation where there was a small chance warp zones and pacifiers may not appear where needed. This will only fix brand new saves and brand new New Game Plus games
-Level restart works on both warp zones and bosses
-Fixed an issue with 00:00:00 level times after replays
