Don't dig the character design too much, seems mostly like generic pretty boy/cute girl anime with lack of detail in the faces, but other than, looks incredibly good.
I hope it's not too scripted though. The 14 min gameplay seems heavily scripted, even a part of the boss battle where the witch girl pops a bubble seems somewhat scripted (if it's actually gameplay then dear god). While scripted sequences on their own are fine, if the game is just a chain of scripted events then that would kinda suck.
Also hoping that the difficulty will be somewhat challenging. Boss fight seemed good, but I know too many games in which a couple people group up to just rush through a dungeon 20 times in a row without any kind of trouble because difficulty is so low that spamming your abilities gets you through the fight.
Other than those concerns it really seems like my type of game. Stats-driven action RPGs are my favorite combat systems. Loved The Last Story and Xenoblade. You get the satisfaction of drafting a good strategy and also the satisfaction of executing it well under pressure. I remember fighting the boss of The Last Story for like 40 minutes because I didn't know there was a QTE you could make use of to deal large amounts of damage, and the boss had 3 phases. If I recall correctly I was constantly trying to outlast the period until rezzing becomes available again after using it, chipping away the health and at the same time keeping track of the ressurection timer, not allowing myself to die with only 2 party members left for like 15 minutes. Shit was intense and oh so lovely. That was a worthy boss fight.
