The evolution-themed game Fly or Die must be one of the best and well-though Io projects. Here you will start as a small and weak insect – just a fly. The task is to fly around and make your character evolve. To do so, you will have to fill your Evolution bar. Gather useful objects and become stronger and bigger, change to other creatures, and reach the top of the food chain in the result. Your attempts will be rewarded by improved skills.
