Right now, the english version is coming out to switch this year. PC version has been announced by mangagamer, but if you need to know anything about them and blvn's, it's that you're gonna propably see it in next century or learn Japanese faster. I got my version of Ooe on dlsite in Japanese + used ocr and a translator to play through it. It was fine, but this visual novel is very complex, plus has some showa era wording, so some people i saw online were better off waiting the century.
Other routes involve 9 characters what are stuck on the island + a secret one. The manga here focuses on Ariake, a crematorium worker that sticks to the mc like glue. If i remember correctly, there also will be Shinbashi hen, which is the second romancable character; a playwright which imo is the fan favorite but the routes are very diverse, ranging from older men to younger, less crazy, more crazy etc. Some are not romances (One character, Hinode is 13 so it's more of a story/character focused route), but most are. Additionaly, Oosaki is the top only so yea. He cracks old men.
Do note that yes, characters die but are stylized as shilouettes. Descriptive problematic elements include things like incest, grape, drowning, connibalism, etc. Its not a fluffy game but a very great one still (づ ̄ ³ ̄)づ
