I go by venharim, and I'm the creator of Ven's Horror Sims, a web-based simulation platform inspired by horror films and reality-competition shows.

I built this site around a simple idea: horror works best when characters feel distinct and choices actually matter. Instead of scripted stories, Ven's Horror Sims uses archetypes, relationships, and probability-based systems to create unpredictable seasons where alliances form, plans fall apart, and no two outcomes are the same. The goal is replayability with personality.

I graduated a few years ago and have worked in the business sector since. What started as a side project to help me move into a product management role quickly turned into a full product in its own right. I've owned everything end-to-end—from defining the vision and building features, to testing ideas with real users, responding to feedback, and iterating in public. Along the way, I've learned how small design decisions affect engagement, how to balance ambition with scope, and how to ship continuously without losing the fun.

My love for the genre started in high school after playing Until Dawn in 2015, which showed me how player choice could drive tension and storytelling. Since then, I've spent thousands of hours with asymmetric and survival-horror games—including 6,000+ hours on Dead by Daylight—studying what makes certain mechanics feel fair, dramatic, or frustrating. This project is my way of turning that curiosity into something interactive and shareable.

At its core, Ven's Horror Sims is about creative systems, playful self-awareness, and letting the audience feel like they're part of the production. I like to poke fun at familiar horror and reality-TV tropes, break the fourth wall when it makes sense, and reward players who pay attention.

It's the most fun I've ever had building a product—and the one that's taught me the most.
