I was really loving the game until I reached the ancient sub, all the pieces start to flicker and also they are really hard to pick up what might be causing this?

I'm trying to play on my Steam Deck, but the list of pieces seems to be halfway offscreen, I'm assuming due to the 16:10 display: https://imgur.com/a/5XNGx2X

I just wanted to say that I really enjoy the art and the light mechanic. Very nice and chill game to play.

Will it get Steam Achievements?

Are there settings for this game, like music volume, sound volume, graphics, etc? Also, I finished a puzzle. It kind of looked like it joined, and that was it. Is there no complete reward message or achievement? I see a wreath on the main page for that puzzle, so does that mean it's done?...
