I have only played this game 15h or so and I can say I have at least 50 hours yet to finish it, and with this I am not gonna reach 100% !
This game is really fun to play, losing wont occur but winning can be hard enough to have you try & try again. If you like to discover every part of a small world this is the game for you.
The only drawback is I experienced some motion sickness probably due to my aging computer but it seems better with low graphics on.
