NOTE: THIS IS NOT REVERSEABLE

After you reset, you will have to earn all of the achievements again

1. Navigate to here and download the file
2. Unzip the file and open "SAM.Picker.exe"
3. Type "2527500" as the app ID, click "Reset" at the top to reset all achievements

Note: When re-achieving everything, the "Creak in the Dark" achievement is bugged and will not unlock, therefore the "Pro Gamer" achievement will not unlock. However, runs can still be submitted if this achievement is missed, since it is automatically achieved when playing through the game normally
