I can tell there has been a lot of thought put into the battle system. While it is complex at the beginning I was quickly able to understand how it worked and found it enjoyable.
At first I felt like this game was going to be really hard, but a few encounters later and I was tearing through enemies in just two moves. I didn't even try to go to the chest rooms, and I went through several special encounters and they felt like the same difficulty as normal enemies. I was especially flummoxed when I beat the boss in 2 attacks XD
