Half of the game is just badly controlled raft-steering game.
The other half is about visiting a few types of small locations that are very similar to each other where you must loot resources and shoo off aggressive boars (as everybody knows, real world is full of aggressive boars, I am attacked almost every day myself).
Hunger meter depletes very quickly and early in the game there is little opportunities to get food.
So as a result, half of my deaths were due to raft crashes, and the other half due to starvation.
The only plus - nice country music.
