Hey I love this its so good and thanks for making it free. Easy to implement too. I use it in my most recent game and will most likely use it in future game jams.
EDIT: I had initially thought that the profanity filter wasn't working as I was in a hurry and implemented it last minute but then I noticed this was not the case. If the profanity filter is on, you type in a profanity and try to update the leaderboard, the console prints a debug log and pauses the preview mode. I thought it had crashed but it only just paused. Just unpause the preview to continue lol. Profanity filter works perfectly thanks Dan
