Personally, I like games that have you work for your reward. I also like games that let you get to know the people you're with. With the fact that this game has a satisfying payoff, if you think the same way I do, you should play it.
That's great, I'm glad you feel that way! The game lets you choose a difficulty that is right for you -- and you don't have to do the hardest puzzles if you don't want. I'm glad you're having fun with it!
