It's nice. Flawed, but nice.
But, unless someone extensively reads the strategy guide, they won't know how to survive in Nightmare difficulty, specifically the Infinity Space stage. It's because of this, that my current choice of person and beast, that I can't win, and you're robbing people victory based on decisions THEY DIDN'T KNOW ABOUT.
I chose Sisily and got the Behemoth beast, and it simply isn't enough. Her damage output (even with spamming Behemoth's special) takes me several minutes to kill one boss, and one hit can nearly kill her. I can manage to make it to Leo through dual Mirage Boots (basically depending on high dodge rate), but even then it's just too hard.
Now that I'm reading the strategy guide, it says Tiamat is the best choice, and a usual high power and agility build. I built her endurance and empathy, and chose Behemoth (because your guide is incomplete and you don't know what perks they have after Tier 3), so I'm just out of luck. The game doesn't give me the option choose a different beast of a lower tier and upgrade it from there, or to redistribute her stats, or continue beyond level 20. The game is basically putting a huge DEAD END sign to anyone who doesn't build correctly to the specifics of winning, and that's bullshit! I have over 7,000 of both gems and I can't spend any on my beast to get a different tier line.
Music is great, graphics need a bit tweaking (or background, I can't tell WTF is going on when my Behemoth ball blasts shoots rays back at me. I'm dodging those thinking its enemy fire).
Stats are nice, making items is nice, but in the end there's no raw data for the other half. I deal 50 damage, okay, but when I go up against a boss, I have no idea of its hitpoints, or how much damage I'd take if it. I have no idea what enemy causes what affliction (random thing runs into me - FREEZE), how much the affliction lasts for or how much damage it does. Then when I look at my Behemoth Breath, says over 19000 damage per second, and that's totally false. When I read "Morale", it just says how often the beasts attack... yeah, okay, but what does the number mean then? A percentage? It's too confusing when the description doesn't give you enough information.
Well, thanks anyway for the good game, but like the first one I played (turn-based RPG), it's the same issue. You HAVE to do this, and you HAVE to do that, or you won't make it. There's simply not enough flexibility in your game in certain situations.
