Pretty substantial improvement over the first game but still far from being a great game. The random encounter rate is absolutely insane, most of the dungeons are gimmicky and a slog to get through and the combat is still barebones and leaving it on "auto" worked for 70% of the game. Besides that, the shaman system is a very interesting idea but it requires a massive amount of backtracking everytime you get to low health.
As for the story, it has some interesting ideas but doesn't flesh them out enough to leave a lasting impact (this point, however, might be due to the awful localization though).
All-in-all, it has Katt in it so it's a good game.
