Alright. Playability was good, with no major bugs or noticeable errors. The scenario did finish when I had explored about 98% of the map, but that's honestly not a big deal.
Points were docked here for two reasons: The game took an extremely long time without speed cheats (steroids), and that after a while it got boring just running around in a group killing lions. It takes way too long to build up, from only three villagers: A town center, a few houses, and extra villagers. With only three wood gatherers and no wood, it's really tough and tedious to collect building material.
Once the rough part is over, it's a bit too easy. With a good group of villagers, you can easily pick off the lions as long as they don't attack in herds.
The fun of this was around the middle, when I had to sneak around lions to collect fish and find berries. It was also fun capturing the discoveries through spear throwing, which triggers the flag on them.
Balance was quite hard, which I enjoyed. The beginning is extremely dangerous, so you must be careful in exploring and ever vigilant on the lookout for lions. The lions would be nearly impossible to escape from if it weren't for the fact that they have a bit of a delayed reaction attack, allowing you to escape by running from them a split second after finding them.
The end took a turn for the easy, which is why this is a four. It just becomes boring once you have a villager tribe.
Two things boost this. The fog terrain, which is innovative and interesting, and the use of discoveries, which is rarely seen. These elements combine to create interesting, if not possibly boring gameplay.
Map Design: 2.5
Standard fare. Grass and forest, with the fog. Shallows boost things up a little.
Simple and to the point, with a one-line story that made me smile.
Additional Comments: If you do, be prepared for a long, bizarre (in a good way) ride, with simple map design.
To improve, just work on adding more exciting gameplay and map design. Try looking at some random guides and high rated-campaigns, and take your favorite parts of the game and translate them to your scenarios.
