The "data.sav" file contains not only 100% of my unlocked achievements, but also my personal game settings. I recommend making a full backup of the "SaveGames" folder before replacing it.

In-game achievements also unlock new items for purchase in your worlds.

A quick way to open the saves folder:

Press Win + R on your keyboard
Paste the following into the input field: %localappdata%\VotV\Saved\SaveGames
Press Enter or click "OK"
