Total game time for 1 quest: 7 hours.
I generally like M3-Games if they can be played without a timer and yet stay challenging. This one can. Objects have to moved away from walls or blocking bricks, frozen tiles must be melted or they won't move, 4 different types of power-ups collected… It also tells a sensible story along the way about Hercules.
Levels are usually 4 M3, 1 HOG, 4 M3, 1 replace-the-artifacts and another HOG. Neither could be skipped but neither was too difficult either. I hardly ever needed hints.
The game tells me I can now embark on another quest with "new challenges and obstacles" but I won't just now.
If you liked „Around the World in 80 Days" but were frustrated by the time pressure than this game might be for you.
