As you can assume from the title this game is a prologue and can be completed really fast. I already streamed the game and uploaded full walkthrough video to YouTube, I will put it here in the guide in case you are interested.
There are only 6 achievements. The achievements are pretty easy and unmissable. if you just started the game as I did and had no idea what to do, and you like wander around like me, you will finish it in 25 minutes approximately, but I think it can be completed in under 10-15 minutes if you skip everything.
