Finished Island on a whim recently, since only absolute madmen watch VN adapations.
Was a pretty decent red herring simulator and yu-no clone, especially in the parts of ending up fucking your own daughter, not so much in unknowingly cucking your wife/fiancee/sister reincarnation for hundreds of thousands of years. Only a shame there was no H content, and ending was a bit too open after setting up the whole mystery of why the fuck was everyone dying constantly.
Went on to take a look at Maitetsu with all bajillion uncensor patches.
Nice train autism so far. Pretty sure MC is either a completely broken sociopath or his balls got crushed along side his sister in the train crash.
