A fun game with an amazing soundtrack and a battle system, which you'll either find pretty weird or enjoy quite a bit.
The first game is the weirder of the two, having you reach max level before the final dungeon, which btw takes around half the game length.
The second game introduces magic, adding a cool new layer of gameplay. The leveling system is also readjusted.
Unfortunately the game doesn't give you a very good idea of where to go and what to do a lot of the time, making you kinda roam around until you figure it out.
