This game appers to be easy because of the fact that you can train for hours and hours without ever advancing in a chapter. But, when you try to go forward with no Tower or Ruins Training, it's extremely difficult. I noted that in one chapter the enemy units jumped five levels on average.
And another thing: but crap I forgot what it was. I'll remember it later while talking about something completely irrelevant, like Teletubbies or something.
