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 Stunning Precision Platformer That Shines​

    Self Simulated: A Stunning Precision Platformer That Shines​

    With a stellar 4.9/5 rating, Self Simulated proves itself a standout precision platformer. Its premise—reclaiming your identity as a digital copy trapped in a machine—adds emotional weight to the high-octane gameplay, where fast movement and instant retries turn every level into a thrilling test of reflexes.​

    The game excels in accessibility and depth: over 100 enemy-and-trap-filled levels keep it engaging, while assist settings (like triple jump) let players tweak difficulty without losing the core challenge. Hardcore mode and a built-in speedrun timer cater to pros, too. Auto-save and optional tips further polish the experience, ensuring smooth progression.​

    Developed by Martin Cremerius-Gauer (2nd Law Games) while camping across Europe—with his wife even designing two levels—its passion shines through. The $39.99 package (premium cartridge, manual, charm) is a treat for fans. Blending Celeste-style smoothness with Katana Zero energy, Self Simulated is a must-play for anyone who loves tight, rewarding platformers.
