With the recent update that expands a couple of places in the game, the devs of the game are gracious enough to provide a legacy speedrun only code for those who'd want to downpatch the game.

To downpatch the game:

1. Locate your game on Steam, right click the game and go to Properties.
2. Go to Betas and put in GoGetThatWR420 in the textbox.
3. Update the game and you're able to play the downpatched version of the game.

If you do want to use the current version, it's perfectly fine! But this is for those who'd want to have a little bit of timesave in the game.
