Crossplay

Is Castle of no Escape crossplay?

Crossplay does not apply to Castle of no Escape: it has no online multiplayer.

Explore the mysterious castle full of monsters and secrets in a quest to collect all the treasures (that will also protect you from the curses on your way) and crush the main boss. The game won't let you exit the castle, no matter how you try. Technically you can win, but there is no end.
