English will always be the default language of any KS release. The one in the physical package is in no way different from the release that will be available from our site, it's meant for people visiting the Kawa-Soft booth at Japan Expo, thus the packaging texts are French.
Making physical releases don't make much sense for us, so it's somewhat unlikely that would ever happen. The only thing I can think of is some sort of super fancy collectors thing packed with posters, artbooks, pins, cellphone straps, the game on a goldplated bandagedheart-engraved USB stick and a pump-up delta realdoll but you all know we're not keen on making KS merch unless there's some twist that grabs our interest so yeah. If you want a physical package the most useful thing is making one yourself (which many fans have done)

<Suriko> I would do it if it wouldn't be so hard to explain to my parents
