Hard Mode is busted. On Normal, bosses can be challenging at times but overall quite doable and the Ruins 'bosses' are challenging, sometimes wiping me at times depending on what enemy the boss uses on that floor.. Switching to Hard mode means that you'll probably get wiped in a few turns due to bosses having high damaging aoes, multiple turns and high crit rates. If you don't believe me, next time you get to boss, swap to hard for the first attempt, get wiped, then switch back to Normal. It's ridiculous. Normal enemies are pretty fine and they can make you worry if you're not paying attention, but they felt fair enough in the first dungeon. After getting pounded by Hastur 5 times in a row though, I switched it back to normal and only looked back once, which was when I got to the Umeda miniboss and swapped back to hard just to see if it balanced out by this point.
I've played about 4 or 5 hours over the past few days and yeah the difficulty curve is really weird. The normal battles are a cake walk which lured me into a false sense of security. Went into the first boss, Hestur or whatever it was called without going back to buy items or restore MP and got decimated. To be honest even after i did go out to heal up it wasnt that easy due to spamming his silly wind aoe. Though I might have been underlevelled since i didnt exactly battle too many normal enemies due to their ease.
I've not gotten to another boss since but the normal encounters in other areas were easy too.
Edit: Sigh, got to the next boss, beat it but the game froze up after saying you won in the battle log....
Finished the game a bit ago. I thought it was decent, but it definitely has problems. I ended up using Enoch, Echidna and Yamaoto-Takeru like the whole game even though there are a ton of Astrals to choose from since I had no real incentive to change due to the game being so easy. Probably not going to bother with the 100 floor bonus dungeon.
I like the modern occult plot so far, but the gameplay feels very cheap, for lack of a better word. The portraits for enemies have no animations, they just shuffle around a bit while flash art numbers pop up.
