I enjoyed the demo for what it was, the gameplay is pretty solid although on normal, and even on hard, it still felt too easy compared to other Soulslike games... beating Chaos? didn't really feel satisfying because he was just so easy, first time I fought him it was just dash in, hit twice, dash to the side, hit twice, dash to the side, hit twice, if he does his AoE, dash out then back in, rinse and repeat... from that distance all his ranged attacks miss because you're so close, and his sword attacks are so easy to see coming because of how they're telegraphed (Is that the word I mean?) meaning that avoiding them is just a piece of piss. Don't want to fight him close ranged? Just stand really far back and blast him with magic as he VERY SLOWLY walks to you, after a certain distance he DOES dash, but by then the damage is done, just move out of the way and run to the other side of the arena... at least on hard mode he seemed to have more attacks and/or was more aggressive so you had to use the shield more often, which still feels like a cheese because the window for it is so forgiving and it blocks ALL damage from EVERY attack lol.
So yeah, TL;DR the gameplay of the demo was solid although my main complaint was how easy it was... I was expecting hard mode to give me a proper challenge, especially considering it's made by Team Ninja lol
