Topic. thank you

I went into this game despite all the negative review you can find not only on steam But after forgiving some very boring general gameplay I got stucked , bringing the fisherman his 5 crabs nothing happens at all and cant even get out his house dev seems to not care game is broken aside being nothing special or enjoyable ...

1. Are there any promotional or exclusive bonuses that I have to worry about missing out on? 2. Is there anything permanently missable, even rewards for beating the game a certain way? 3. Are there any rewards for having save data from a different video game? 4. Is this game identical on all platforms, including the Switch version having an in-game achievement system? (Do the achievements even add additional challenges that wouldn't be done for full completion, anyways?)...
