Welcome to Krayfish Entertainment, home to all the games, music and stories by Krayfishkarl. I’ve been creating characters and worlds since the turn of the millennium.
About me
My name is Karl “Krayfishkarl” Ast. I am a professional software engineer though I moonlight as a hobbyist game designer. I previously served eight years in the United States Army as both a Field Artillery Tactical Data System Specialist and an IT specialist. I also have a Bachelor’s Degree in Computer Science.
When it comes to creating games, I’m a jack of all trades. I’m a solo developer who does all the programming, modeling, music composition and more.
History of Krayfish Entertainment
I began my creative journey around 2002 where I made animated cartoons from PowerPoint, laying the foundations for what would eventually become the Karland Universe, the first of my worldbuilding projects. I would upload them to several different precursors to the Krayfish Entertainment website.
The year 2005 marks the creation of Krayfish Entertainment’s first video game Zackulback Adventures. It’s a short 2D platformer created with Multimedia Fusion at an engineering summer camp within one week. In the years that followed, I would create many more games of a similar style.
The present day Krayfish Entertainment website was created on January 5, 2013. I would not only release several new browser games, but also port many of my older games to be playable via HTML5. I would also register Krayfish Entertainment as an LLC in 2021.
Krayfish Entertainment’s first commercially published work was the video game Droplet: States of Matter, released on September 30, 2025. It is currently available to play on Steam.
Other works
While Krayfish Entertainment is primarily for all of my personal works, I also host other community projects. They are as follows:
- Galactic Crucibles – A large-scale sci-fi worldbuilding project that takes place in the Crucible Galaxy.
- Erudite Tales – Another worldbuilding project set in a medieval fantasy world.
- TVRS Wiki – Home to the PHIA Phorce, a science fiction setting inspired by The Virtual Reality Show YouTube channel.
