“Sentinel” Now Available On Steam

Today we have a new kind of tower defence game available, the audio tower defence title “Sentinel” just released on Steam!


Sentinel is an interactive audio tower defense game. It mixes strategic gameplay with a dynamic music system. The game takes place on a sequencer-like grid. As you add defenses, collect resources and destroy enemies, musical elements are triggered in time to the backing music. It is inspired by music games such as Rez, Lumines and Soundshapes.

Sentinel began as a simple experiment in creating an audio sequencer in Unity that was then expanded with the idea of setting a tower defense game on this grid. The results were interesting enough that it developed into my first commercial release, taking around 16 months to complete.

I love all things Linux, my favorite distro being Ubuntu followed closely by Kubuntu and Linux Mint (Cinnamon and KDE). As far as I'm concerned Linux is the future of gaming. Lets make the world as open and transparent as we can!
