i finished this game entirely in Japanese, and i gotta say: it's honestly pretty great. it calls itself "mini", but frankly, it's longer than a lot of other games i've played, and definitely worth the time
it's a really enjoyable experience, and while i still had a good time without exactly understanding what was being said, i think that having it in English will make it even better--the only thing i'll really complain about is the fact that, once you're at the end of the game, there's no option to use the extra customize features (like how it seems the school has many extra outfits in the gallery that aren't accessible for regular gameplay) in actual gameplay--so, if you're a weirdo like me, who enjoys running through the halls and being chased in the game, you are stuck with whatever outfits and such you can regularly get.
if it weren't for the fact it sounds like Kagura is gonna translate this, i'd do it myself
