OSK is a short side-view adventure platformer made in the «2.5 D» format. Here you will find an unusual story of a small squirrel and the world burning around it. The game takes place in an unnamed forest, in the depths of which a sleeping volcano was located. But suddenly he woke up and the world began to die before our eyes from the raging lava, fire, and fires. What happened? Why did it happen? And what about now? You will find the answers to these questions during the game, but they are not so important. Where it is more important to be saved. And for this you will need to go to the top of the highest tree, located nearby.
