How interactive can I make "evil portal"?

This was removed in the r/flipperzero subreddit, so trying here.

Not really interested in the 'evil' aspects of 'evil portal', but more wondering if I can turn this into some sort of game.

Basically can people interact with them page at all? Say we can start chatting via the page, or I can build a simple game that a few can play at the same time
