World Isekai Red Eyes is a fantasy game by Fapple, made with Ren'Py and presented through animated 3DCG art. You play a nineteen-year-old unemployed boy who is killed by goddesses and moved to another world. There, a virus has left most men weak and childish, while a second affliction called the Red Eyes disease spreads among the population. The story mixes harem relationships with a school setting.
The current build is version 7.3.0, released on October 30, 2025, and development appears ongoing. It runs on Windows, Mac, Linux, and Android, with English, Italian, and Spanish text. The game is uncensored. This update adds Chapter 7, continuing the goddess storyline and revealing what happened in the mysterious forest. It also introduces a new room encounter, a school exploration phase with a mini-game that unlocks a hidden scene, and a date with Grace featuring a sexual mini-game that can be disabled.
Developer's description
You are a 19 year old neet boy (neither work nor study) who is killed by some "nice" Goddesses and taken to a world where, due to a mysterious virus, men have become impotent and regressed to an infantile state. But another mysterious disease afflicts the remaining population.
