About the Developer

Bio

Name / Studio Name

Martin Cremerius-Gauer / 2nd Law Games

Location

Duisburg, Germany

How It Started

It started as an idea to build a playable portfolio for my personal website – and that’s when I discovered GB Studio. From there, I was hooked.

Other Games / Projects

Self Simulated is my first “real” video game. Since then, I’ve started work on Fuse Dash, an arcade-style action platformer for the Game Boy Color that’s still in development. I’ve also helped with level design and QA testing for other indie devs' projects along the way.

Fun Fact

Self Simulated was made while camping across Europe – Italy, Norway, Denmark, England, Scotland, and the Netherlands. I worked entirely on my laptop while on the road. Oh, and my wife designed two of the levels!

The Idea

Why I Made This Game

Making a video game has always been a dream of mine. After watching Game Maker’s Toolkit’s video “Why Does Celeste Feel So Good to Play?”, I wanted to try building a platformer that felt just as smooth and satisfying – on the Game Boy Color, no less.

What Makes This Game Special

Just the fact that it exists! When I look back at the time, effort, and learning that went into Self Simulated, it honestly feels like a miracle. Like – I made a video game! That’s freaking awesome.

You'll Love This If...

You enjoy tight, responsive platformers – especially if you like mastering precise controls.

Inspiration / Influences

My aim was to create something that feels like a mix between Celeste and Katana Zero – but on the GBC.

Favorite Feature

Definitely the assist settings. They let players tweak the game’s difficulty to match their play style, which makes it more accessible without compromising the core experience.

    “Self-Simulated: A Retro Gem with Modern Depth”

    I’ve been playing Self-Simulated from ModRetro and I really enjoy it. The game feels both nostalgic and refreshing, combining retro-inspired visuals with smart design choices that make it stand out.

    What I like the most is how it balances simplicity and depth. On the surface, it looks like a classic throwback game, but once you start playing, there’s a surprising amount of strategy and replayability. The mechanics feel tight and well thought-out, and every session leaves me wanting “just one more run.”

    The presentation is also impressive — the art style captures that old-school charm without feeling dated, and the soundtrack adds a lot of atmosphere. It’s the kind of game that makes you smile because it reminds you of the golden era of handhelds while still feeling modern.

    Overall, Self-Simulated is a hidden gem. If you love retro-inspired games or just want something fun and addictive to pick up and play, I definitely recommend it.
