It could be good, but it might be a bit tiring to be broadcasting all then posts all the time (well for me at least, I'm lazy with that kind of stuff). It sounds like you took inspiration from the game Balderdash. It does sound good though! Although what does the name really mean, 'change the speech and fun' or something (sorry, can't quite decode it)? Maybe a good name would be "toki kule"? Because, you know, just stating exactly what the game is isn't always the way to roll with games, e.g. Scrabble isn't called "make a crossword" and Balderdash isn't called "think of fun word definitions". It's just a suggestion though. I might play this actually, but I'm trying to get more toki pona speech into my life since I haven't actually spoken to anyone in toki pona IRL.
ale li pona.
