The game itself does not change between Steam, Nintendo Switch 2 and PlayStation 5. Story, stages, the card system, the six characters and the 20 to 30 hour length are identical everywhere, and all three versions are single player with no online mode.
What changes is everything around the game. Steam is the only storefront that sells all five subtitle tracks without a regional release. Switch 2 is the only Nintendo version, and there is no Switch 1 build. PS5 is the only platform where a pre-order bought early access, through the Digital Deluxe Edition.
The soundtrack splits too: Steam's Deluxe Edition carries 30 tracks, the console Deluxe Editions carry 11. That single difference is worth more than the price gap if music is why you are upgrading.
Each page in this section takes one platform and covers what it actually gets — features, subtitles, boxes and price — rather than repeating the shared parts.
