Try Roblox! Unless you haven't yet. I was SO impressed. Everything works as expected. 5 minutes after starting the game making kit I totally understood why Roblox is worth billions. It just works. It's magic. All can be scripted, but also any 6y.o. can use it.
I'm still recovering from the analysis of a chat with my best friend. I think it was on point. And I don't think it's Barnum Effect (although we obvs haven't done a perfect study).
We intended to launch it properly, but then we saw that it's really hard to get people to share their chats, hence open sourced all. Please share any feedback, as it was built quite quickly.
P.S. It's also password protected! And it takes a while to process, but it works.
