> It is hard for me to read a text that is set only in hiragana (as in the Japanese version of Animal crossing on Switch for example, the characters only speaks in kana, with no spacing separating words...

I'm very curious as to why Nintendo made this choice!

Is it because the game is designed to be welcoming to children? In which case, why not use furigana and use it as an opportunity to learn Kanji though repetition?

Is it supposed to reflect the simplicity of a back-to-nature lifestyle and the characters therein?

I'm inclined to suspect is the latter of the two; especially if kana is only employed in character speech while other parts of the game use Kanji.

Has anybody played the Japanese version? Can you speak to the use of Kanji in the game?
