Thanks for the feedback!
Random level is indeed a great idea.
As for chatting we have a Discord server. Decided ages ago to go with Discord instead of IRC or Matrix as it is way more popular nowadays, notably in gaming circles. Integration in game of the Discord chat would technically be possible but a bit clanky to use with a NES controller. Support for the family basic keyboard could be a fun solution but there are so few units in the wild that it would not be practical.
