This game with its relatively short play sessions and non-stop moving makes it really addictive which is definitely a 5 star for engagement for me.
People are saying that generation was weird but I think that as long as there are no dead ends so that you can keep moving, it would suit the gameplay.
The level of polish is great but effects like screen shake could make it even more addicting!
And the ending of having the items scroll with their unique names and value is so clever and great to see!
