The main video game takes place in a dark environment where we will need to understand how it works to move around and find our answers. For that we need to interact with the elements around(creatures and props) to move around. For all these interactions we have two ways of doing it: One is by using sounds (the "kamak" sound or borrowed sounds from nature) and the other is by moving around. Each of those actions will trigger consequences that could help you or not to move forward.
We have basically 1 inner sound (your kamak, soul) but also you can learn an extra sound, a sound that helps you in some situations and you are able to learn just one sound each time.
Each level has its own inherent puzzle and to decipher it we have to interact with it, so we just need to discover what each level needs.
The player character can mainly interact with the vegetation the light and the creatures around. Everything in the level has some symbolism.
