Here’s my latest release: XY Cannon, an open source game for Ouya and Android. A tribute to Jeff Minter’s Laserzone. In this abstract shooter, you control two cannons at the same time.
Implemented in Java/OpenGL ES 2.0, with procedural shaders and a ton of trigonometry! You have to see the game in motion to appreciate the graphics
