i've played through this game in full japanese; it's alright, but definitely not much to write home about. if nothing else, i was able to very easily get through without a translation, the only part i got stuck on for a bit being that there's these two racist shops that won't let you through unless you change your skin color (i don't get why they do this????), but everything else i got through without trouble.
it DOES make all scat content optional, which is very nice, and for every scene except for one you can choose the girl's skin color, which is pretty nice.
however, the game itself is like maybe 20 minutes long at maximum, and it has very few scenes; some of them are decent, but imo they're not THAT good
