Hi everyone!

Game Concept

My Idea “The Vortex Defender”  is based on Space invaders, but instead of the enemies move from top to down, they come from a vortex in the middle to the limits of the circle, and sometimes (maybe most of the time) to the direction of the player.

The enemies move, not only in straight lines but defined by paths (some circular, others more complex).

The navigation of the player is defined by the movement around the circle, not freely inside it. This means that, it rotates around the circle maintaining the direction to the middle of the circle.

The input comes from the keyboard and mouse.

In the keyboard, the player uses the right and left key to navigate around the circle. While the mouse inputs are described in the image.

In next post, I’ll describe power ups, chain combos by killing enemies… and more. Now I’ll start prototyping in Unity3D.
