I like the look and the smoothness of how it plays, but there obviously isn't much to do.
Sound would add a lot. Plus some level of interaction. Or even explanation about what the skills do. I have each of them leveling a different skill. The Luck guy is way behind the other 2 (levels 10, 10 and 5 at this time), but I don't really see any difference between the three of them as they walk around and mine.
