"Brave your climb. Face your punishment. You were banished here for a reason, Ocnus. Perhaps your answers await you at the peak."
Ocnus Theory is a challenging 3D platformer that will test your creativity, reflexes, and ability to rise from a painful fall. Navigate the sandbox environment and build yourself into the Ocnus you need to be. Pick up blocks, fruit, fish, and anything else that will stick to your core to match the needs of your climb. Stuck trying to climb a particularly thin cliff? Perhaps a change in shape is in order. Rearrange yourself and try again! Just be careful where you fling those blocks. It would be a shame if they were lost to the sea far below. Though the climb ahead may be daunting, with a little creativity and patience no task is impossible.

Amidst a mountain of corpses you climb, higher than any others of your species. For what is an Ocnus without an endless and futile struggle? Reach the peak and ascend to your full potential...
