JP/CN-only... it was recently trademarked in English in Japan, as "Natsu-Mon: 20th Century Summer Kid", so I guess it's just a matter of waiting on the global publisher to announce/finish the EN loc.

I know a lot of people weren't satisfied by the Shin-chan game and might be wary of jumping into another not-Bokunatsu so soon after that one but I can confidently state that this game is much truer to Bokunatsu, and that one shouldn't worry that it's going to checklist them to death just because it's "open-world".

Incidentally, the Switch version got some paid DLC today, and I do wonder how they'll handle that when the English version is released, and whether there might be any other loc-specific changes/additions in the works... any degree of character/gender selection would be welcome, for a start.

just saw they added a note to the Steam page: the English loc's being added on August 6!
