Ooh what is the name of that game?

Depersonalization. The official translation is just barely above raw MTL - it's very tough to read unless you've got experience reading things via Google Translate. The devs are very much not native English speakers.
Fixing it's translation is a bit tougher since, unlike VNs, lines can be out of order, and finding context is harder. I've got the first ten minutes (the castle section) updated with a better English translation, I'm hoping to push out a release once I finish the entire prologue story, with a sizable chunk of menu and combat text being updated as well.
Amusingly, the first ten minutes has a surprise guest appearance from SCP-3999. :D
