Just spent all day playing it (a few hours three player, but the vast majority with only one other guy) and it's fun as hell.
At first you get nervous because dungeons are very short and easy and one drop of the Myrrh tree fills like 1/3 of your bucket (thus 1 year in the game is three dungeons).
But around year 3 or 4 the difficulty and length of dungeons seriously picks up.
The game seems more easy to manage with two people, but the chaotic fun of four player is tempting. My friend had tests to study for, so I may not get that until this weekend. It's still highly reccomended, as long as you have at least one person who can reguarly come over and play it with you.
More info later. This game also seems to cause a lot of confusion, so I'll answer any questions people might have about it.
