What could be more simple. Instanzia is an endless play space shooter. You’re the good guy and the aliens are invading. Just shoot them down and stop them getting to the Earth.
Use D and A on the keyboard to move left and right then just watch as the aliens explode – but don’t get hit directly or you’ll die a painful death and have to start again.
You can talk about the game or share your score in the Instanzia Forum.
