Hey, thank you for trying and giving feedback! Can you please tell me on what device and operating system you are trying it on so I can debug the tutorial getting stuck?
Also, for the game rooms, the ones that already exist may be in-game already. You can create a new room and start your own game or join a room that is in "waiting" status. If you join our discord, I would love to play test a session at your convenience and get further feedback from you. Thank you!
