I finished the "base" part of the demo, which I assume is the same as the start of the full game (since it creates a clear data save which you can use in the full game). This unlocks another part deeper into the game with more combat options, but I don't think I'll try this as I never enjoy being dropped into a developed character without the learning experience along the way.
Even the first part of the demo is pretty substantial. Granted, it's extremely story heavy with only a few moments of freedom, but I guess that is typical of early game JRPGs. What is also typical about that, is that the combat is far too simplistic and easy. It seems like style over substance, which is not exactly unexpected. But the good thing is, it is actually fun. Against basic mobs button mashing seems the way to go but the bigger fights are pretty cool. Still easy though, we'll see if the final game ups the challenge.
Performance remained an issue throughout, though less so in the combat-heavy sections. It is clearly not where it needs to be in this demo and if the game launches in this state, I would advise anyone to hold off on buying it. Motion blur is really bad in framerate mode and I tried quality mode for shits and giggles, it's quite possibly the worst blur I've ever seen.
Feels like you're drunk as feck.
All in all, I came away from it feeling it shows decent promise, but needs some work. Unless reviews are terrible, I'm getting this at some point.
