Crossplay

Is Choice Chamber crossplay?

Choice Chamber is only released on one platform, so there is nothing to cross-play with.

Steam's own store page lists cross-platform multiplayer for Choice Chamber. That confirms it exists, but not which platforms pair up.

A crowd-sourced action game designed for livestreaming where viewers play along via the chat to change the game in realtime as you play. Players constantly give feedback that changes how the game evolves, from power ups and enemies to obstacles and rule changes. The game world is procedurally generated based on viewer input, wildly changing the difficulty and surprises each time you play.
