I have been working on a small space shooter game in my free time.

It took me quite a bit of time, given that I had to take care of most of the tasks by myself:
engine programming, 3D modeling, texturing, effects, scripting, gameplay…

The game is now released on Google Play and there is a Javascript/WebGL port also available.

Head over to the game page on Breaking Byte to try it!
