A new version of RPG Playgound is online where you can restart your game. This is a must have feature for when you start killing monsters (or when getting killed).
And, I have a little surprise for you: Press the ‘f’ key inside an RPG Playground game and find out (not in edit mode) :). It’s currently only visual, so it doesn’t impact the game yet.
The ‘f’ key will be replace with something better in the future, but for now it is still hidden functionality.
