I've put a couple of hours into it, several minutes at a time, and I really enjoy this game. The combat and party building are fun, and I like how you can buy things for the basement you're playing in, and they actually impact your game.
There are a couple of interesting twists in party building:
- You start out with only two people, and have to buy the rest of the party at increasing (but not excessive) amounts of money. In-game money, that is. You can choose to IAP more if you want, but you don't have to by any stretch. You can grind for it without much pain. I actually like this, because it makes you think about who you're putting in the party, and it makes those first battles against rats a little more tense than they would be if you already had five party members.
- When you bring someone into the party, you have to choose their class (duh), but you also have to pick who's playing them. And each person has their own benefits. I started with a paladin and a warrior. The paladin is a businessman, who gets a 10% bonus to all XP gained. The warrior is "Wolvie," who regenerates 1 HP per turn. I later added a rogue played by "little brother," who gets +5 to initiative, and a cleric played by "E.T.," who regenerates 1 MP per turn. Can't decide who to add to the party for my last slot yet.
