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

    Self Simulated es una propuesta atrevida que juega con la idea de la simulación y la conciencia de una forma inteligente y muy bien ejecutada. Desde el primer contacto, el juego invita a experimentar y a observar, más que a seguir reglas estrictas, lo que genera una sensación constante de curiosidad. Su planteamiento, aparentemente sencillo, va revelando capas poco a poco, recompensando al jugador que se toma el tiempo de explorar y reflexionar sobre lo que está ocurriendo en pantalla. Es una experiencia que confía en la inteligencia del jugador y no tiene miedo de ser diferente.

    A nivel sensorial y conceptual, Self Simulated consigue destacar gracias a una atmósfera cuidada y un ritmo muy medido. No busca la espectacularidad, sino dejar huella a través de ideas, sensaciones y pequeños detalles que permanecen después de apagar el juego. Es uno de esos títulos que se disfrutan tanto jugando como pensando en ellos después, y que demuestran que el videojuego puede ser un espacio para la experimentación y la reflexión sin perder el factor lúdico. Una experiencia fresca, original y claramente memorable dentro del panorama indie.

    Modern feel in a retro title

    Fast paced, cool narrative, and feels extremely modern on a retro title. Even my teenager is addicted to it.

    Self Simulated: Hard, Fun, and Kinda Nostalgic

    Self Simulated turned out to be a really fun game. It’s got that classic 2D platformer feel, but with some cool time‑based twists that keep things interesting. One thing I loved was the quality‑of‑life stuff — instead of restarting the whole game when you mess up, you just start back at the level. Way less rage‑inducing.

    The difficulty was honestly perfect for me. Some levels got pretty tough, in that “okay fine, one more try” kind of way. It gave me big Impossible Game vibes from when I was a kid, mixed with a bit of Mario charm. Overall, it’s challenging, fun, and definitely worth checking out if you’re into platformers.
