Background

NeonBlast! was created over the course of about about a week and a half taking a couple of hours each day. I made it as a sort of simple 'palette cleanser' after having spent a long time getting the demo of my last title, Frank&Steve ready to release.

I had the idea to make a slight twist on the planet defender formula by having a shield that changes thickness. A thicker shield gives more protection and a higher points multiplier but also reduces the amount of time you have to react to incoming asteroids before they strike it.

My original idea was to have the shield split into sectors that would change thickness independantly as they were hit or absorbed a power pod. When a sector was breached and an asteroid struck the planet there I was going to have that part of the planet on fire with the player unable to move through it. This would have continued until the player was in a sector of the planet that was hit by an asteroid. I dropped that as being overly complicated after making a basic prototype.
