First off, this game is free, so you lose nothing but time if you try it out and don't care for it. However, if you're a fan of the old-school point-and-click games of yore, and pine for the days of Sierra like I sometimes do, this will be right up your ally. You do need patience, as it's slow going traversing the map, but that's the nature of the beast. Battle vargs, troll, brigands and more as either a warrior, rogue or spellcaster, and save the world from Ragnarok.
The only thing I don't care for is how they've made the need for sleep and shelter function. You can turn it off (good! I don't like bothering with those types of things), but that also puts the game in the easiest mode for all battles, too (bad, so far the fights I've encountered have been too easy on this setting.) The solution is to play fast and loose with the difficulty setting; I have it on a more difficult setting until the game indicates I'm going to die of exposure (for crying out loud, put on more than a cloak! what is with people underdressing for the weather in games?!) or hunger, and then I turn it down and continue on with that setting until I eat, sleep or find somewhere warm to recover.
Don't let that put you off, though. It's a terrific little game and honestly, I feel like they're doing themselves a disservice by giving it away; I'd have paid for it. In any case, give it a try. I'm thoroughly enjoying it and highly recommed it.
