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.

    A Precision Platformer Masterpiece!

    I popped Self Simulated into my Chromatic and was hooked immediately. This fast-paced action platformer from 2nd Law Games (published by ModRetro) lets you play as a robotic version of yourself — an amnesiac machine fighting through over 100 challenging levels filled with enemies, traps, and tight platforming.

    Controls feel incredibly responsive, with quick retries keeping the momentum high. Custom assists like triple jump make it accessible while hardcore mode keeps veterans sweating. The pixel art pops beautifully, the chiptune drives you forward, and the story about reclaiming your identity adds nice depth.

    Short, addictive, and packed with secrets — it perfectly captures that classic GBC feel with modern polish.

    A must-play for any Game Boy Color or Chromatic owner.

    I bought this game because the mechanics looked cool and boy oh boy they delivered. The mechanics and gameplay are 10 out of 10. The music? 11 out of 10.
