Hi, I'm being dumb, can I get a little clarification on this aspect of the Flash Revival Challenge?

• Must incorporate multiplayer, clicker, or be modernized with hybrid ⁄ hypercasual style gameplay.

For a multiplayer browser game does that mean something like old-school shared keyboard or hotseat-style?
Also, what would qualify as hypercasual? I feel like mechanically a lot of older simple flash games mostly fit that definition.

It's a broad requirement, so I wouldn't worry too much - as long as you get inspired by some Flash games from the past you'll be fine.
