Koya Rift is an action-packed platform shooter that is built around circular, adaptive gameplay that emphasizes replay value by challenging the player with procedural content tuned to their skill level.

Below ground lies a web of tunnels and caverns that is different every single time you play. It’s impossible to know what awaits you behind every corner. Procedural generation isn't just in the level – all of your enemies will seem different too. Their size, speed, color, health, damage, and weapon behavior will be unique for each one you fight.

One gun may fire large, single shot energy blasts that slow down and weaken all enemies in a large radius, where another gun will shoot bursts of many bullets that curve in every direction with a waving motion, another gun that fires several shots at once but can pierce through walls and home after enemies, and another that heals and enhances your
