Real-time planetary collision sandbox powered by SPH physics: smash planets together and watch the destruction and its aftermath!

A Hole In Space
A "small" universe simulation, where you play as a black hole and try to absorb the whole universe. You decide the size and shape of the universe. Could also be used as a less meaningful CPU benchmark.

SimpleRockets
I am excited to release my first game on Steam! SimpleRockets was released in 2013 for mobile and I've put a ton of work into it to get it ready for PC and Mac. It was inspired by KSP, and it offers a simpler 2D experience for building rockets and exploring space with realistic orbital mechanics.
