I booted this up not long ago, and was very excited to play it as it's beautiful and interesting, but as of right now it seems that the in-game video, be that the separate documentary style insights or the in-game video they show during phone calls with your colleagues, doesn't work.

I emailed their support email they have provided in the discussions and they responded very quickly saying that they are aware of the issue and are working on it.

For now, I have to give this a thumbs down and warn other Steam Deck users that although it's tagged as verified for Steam Deck, it's broken right now.
I hope to update this fairly soon to a positive review.

for everyone who misses endless ocean. a nice relaxed game, not as long or..cinematic as endless ocean but the story is cool and the swimming feels great

this game is so fun and the brine pool is the best place
