The game is very good- its much like the Elder Scrolls Series.
The Good:
World is interactive.
Variety of Enemies.
Unique casting System (hold ctrl and draw glyphs w/ mouse in certain order and release to cast)
Fits its own story (there are few people because the sun has burned out and they all live underground).
Cooking of raw meat by putting it by a fire.
Combination of equipment to create new items is very unique and responsive.
The Bad:
You will get very very very tired of seeing rocky walls and torches. Almost (if not all) of the game is set underground.
In order to access inventory, it is necessary to switch in to "cursor mode" where your mouse can move freely through your field of vision but only when you press it against the sides does your field of vision move. This causes a sort of mismatch in control and is very hard to get used to.
Thousands of Rats. I'm tired of killing them and my character can really enjoyed the cooked meat all that much.
There are only 4 character models in the game, that gets a bit repetitive.
Overall the bad cannot mar this game too badly. Still a good title for those who enjoy an Elder Scrolls experience.
