Miasmata is an "exploration" game, you wake up on an island and have to find plants to create an cure for the disease you're suffering from. You have to wander through the forests, spot and collect plants, then carry them back to somewhere you can identify them and their effects.
You are also chased by "something" during all this, but I won't tell more about it here ;)
What makes the essence of that game is the Cartography Mechanic. Basically, you'll have to build your map on your own, not to get lost. To reveal the map, you have to stand at a particular spot and aim with your compass to 2 known objects (houses / statues / ruins) that you know, so you'll be able to triangulate your position and reveal the map.
Then, the "how to get in the forest without being lost" will make your brain cells works.
The graphics are beautiful, every tree has been "hand-placed" by the two developpers (they have made the entire game, including the physics engine, on their own... that's incredible).
+ Awesome graphics, really (but don't hope playing with a low-end GC), better than some AAA Games
+ The feeling of being "lost" on that Island ; this is the sole game where I really had the feeling that I was lost xD
+ A real "exploration game", where you're thrown in and don't know what to do at first
+ The Cartography mechanics, quite unique if you like it. It serves the "I am lost" feeling
- English only, do not buy if you only speak your native language (other than English)
- Your character has soap under its feet (not actually, it's realistic, but too realistic xD)
~ The whole game relies on exploration, there is (almost) no ennemy (except the controls)
~ If you don't like the cartogrpahy system, you won't like that game
[Conclusion] : If you're ok with English, like exploration, wouldn't be bothered by a lack of ennemies, have a good GC and want to really feel "lost" in a game, give it a try ;) 8.5/10
