About Ultimate Walrus

Hello! My name is Sebastian Janisz. Ultimate Walrus is the moniker under which I make indie games. It has been a two-person operation since my girlfriend Liana Sposto started doing art for the games several years ago.

Some of the games are collaborative, but I made many of the games here by myself from scratch, and still do solo projects from time to time.

Please send your questions, comments, suggestions, or inquiries to .


I am available for freelance programming, as well as freelance game design, music, and web development. I do sound & music and have multiple artists on call so we can do everything from modular tasks to making an entire professional-quality game for you if you'd like, 2D or 3D.

More about me:

I consider myself to be one of the best programmers around, regardless of the task. You will be hard pressed to find a readily available programmer who can code as aggressively fast as I can while still keeping it clean and maintainable, let alone one with my breadth of experience!

Feel free to email me at .
