A 2.5D sidescrolling action/adventure game, where you control a swarm of likeable and very cute creatures called Lumini. Lumini are the inhabitants of an alien planet, that they share with all sorts of dangerous and hostile critters. It is your task to get them through this beautiful, but harsh, environment and bring them to safety. During your travels, you will painfully lose some of your swarm members, but at several points in the game, you can breed new and possibly more powerful Lumini at the mysterious crystals, that seem to attract your sturdy friends. Can you help the Lumini migrate towards a new world?
