Ghost House 3D

Blast, stab, gamble and loot your way through a haunted first-person horror roguelike remake of the 1986 Sega Master System classic, Ghost House.

Fight bats, zombies, spiders, mummies, ghosts, fireball fiends and Dracula himself as you hunt for keys, smash coffins, raid shops and uncover strange upgrades hidden deep inside the manor.

Stack wild power-ups, grab new weapons, hit lights to freeze rooms, befriend friendly fruit, find gold in fireplaces, then risk it all at slot machines and gambling tables.

How to play: Kill Draculas to collect gems. Collect all five gems to reach the next floor. Climb all five floors, then face the MEGA-DRAC on the roof to escape the nightmare.

I grew up with a Sega Master System and Ghost House was one of those games I never stopped thinking about. The music, the atmosphere, the mechanics, it all just clicked.

This started as a personal project. I just wanted to make a game I could actually play. As a graphic designer with a basic HTML/JS coding background, I used Claude AI to help me write a Three.js backend and debug the code. Without it, this game simply wouldn't exist.

I never planned to release it, I just wanted it for myself. But the further along it got, the better it felt, so I added tutorials, an intro sequence and tips for anyone (and let's face it, most people) who have never heard of the original.

Feedback and comments are very welcome. If enough people enjoy it, I'd love to expand it properly, ideally stripped of the Sega IP before any fun legal letters arrive. (Hi Sega, if you're reading this, please consider it a loving tribute from a lifelong fan.)

I hope you enjoy playing Ghost House 3D as much as I enjoyed making it. If you do, a rating goes a long way.

P.S. A big thanks to Insym, whose streams of indie horror games were a huge inspiration for getting this finished. Watching him play and showcase other indie devs gave me a real sense of what makes an indie game worth playing. If you haven't checked him out, you should.
