Extremis is a first-person puzzle game set in a beautiful archipelago. The remnants of a once great civilisation adorn the islands, but the only inhabitants that remain are the various animals that graze and roam amongst the trees.

Against the clock, you must solve eight complex puzzles, each somehow connected to the various islands, using nothing but your eyes and ears. But be careful; three mistakes, and it's all over.

Extremis is currently in pre-alpha. It will be available to download from and the Discord Store.
