Psichodelya

Psichodelya is a vertical shoot-em-up game set in a futuristic environment where two races of mechanized alien species are waging air warfare over Earth-like pieces of land.

The player controls one of 3 playable ships, dodging heaps of bullets and killing wave after wave of enemies for points in single or 2-player local coop. Each ship has a colored shield that protects the player from bullets that are the same color. Enemy ships are also color-coded, making them more vulnerable to player shots of color opposite to their color.
