Isekai Bastard -v0.1.1d- Irta- Bastard-sama -
Forget "Karma." This patch introduces "Bastard-Sama's Favor" .
New Buffs/Debuffs:
As this is a v0.1.1d build, we are looking at the foundation of the game. Most titles in this genre use a mix of Ren'Py visual novel storytelling with light RPG or Point-and-Click elements, and Isekai Bastard follows suit.
What stands out in this version:
The title "Isekai Bastard" sets the tone immediately. Unlike the traditional "hero summoned to save the world," the protagonist is typically cynical, opportunistic, or outright lecherous.
Given the title "Isekai Bastard -v0.1.1d- Irta- Bastard-Sama", we can speculate on several aspects:
Isekai Bastard is an ambitious project. It targets a specific niche—the fan who is tired of playing the hero and wants to indulge in a darker, more selfish power fantasy.
Pros:
Cons:
Rating: 7.5/10
If you are looking for a new Isekai title to follow and you don't mind (or actively enjoy) a villainous protagonist, Isekai Bastard is absolutely worth keeping an eye on. Irta has laid a solid foundation here. We are excited to see where the story goes in future updates.
