Crossplay

Is Dragon Crystal crossplay?

Crossplay does not apply to Dragon Crystal: it has no online multiplayer.

A roguelike "dungeon" crawler that leads you through 30 levels on your quest to find a way to return to your own world. You're caught in a fantastic world of unearthly beauty and deadly demons. You'll pass through thirty worlds in search of the Magic Goblet. There's no way out of this musical nightmare...until you find it.
