I found this to be a very addictive game, especially playing it on the computer. It's very fun and visually cute and it takes a very long time to tire of it. You can summon many skills and have many strategic battles which makes this game very educational in critical thinking. Bosses can be a little scary, but you also need to think in order to kill them. It tends to get boring though, because the same thing is repeated in every level and the difficulty factor only grows slightly enough that it is barely noticeable for every level.
