Just beat it.
This was a darn fine game. Good dungeons, some awesome bosses, good synth/loot system. A++ music like always. Great graphics/art, especially in those last 5 sanctums. Even the story didn't bother me cause I just went tap*tap*tap through it and it felt like an old-school 16bit storyline, which just led you from one dungeon to the next.
The final boss was INTENSE. I screwed up bad on the 2nd part because it hit so hard with the flame hands so I used ALL MY ITEMS and beat it with 1 char alive and like 10hp. So I started the Adol form with no items ^^; After a try or two I thought it was still possible to do even without items, so I kept retrying and getting the patterns down and then I BEAT HIS ASS OH YEAH. It was one of those "adol has 100hp, the boss has 1000hp, CAN YOU DO IT" endings and I did it and it faded to black and sooo good.
Took me about 16-17 hours total. I skipped all the sidequests outside the titano hunts and didn't bother talking to npcs really since who cares about the story, I just wanted to slash things. Just went from one dungeon to the next to the next and thought it was paced pretty well.
Only complaint is that outside of the first few bosses and the last boss the game isn't that super challenging Ys that forces you to learn and dodge boss patterns.
Top 5 arpg materal here imo. 1. Ys Oath, 2. Zelda LttP, 3. KH BBS, 4. Zelda OoT 5. Ys Seven,
