Overall, I'm really enjoying myself so far. It definitely lacks polish, mediocre writing and pacing, and only partial voice acting. Still, it's been quite fun exploring the anime-themed world, customizing my character, dancing with strangers, and fighting bosses with friends. I do hate that the story is time gated, but there's enough other things to do to ease the pain.

I've noticed since coming back to the game that it constantly crashes. No matter how much I lower the graphics, and disable things. I've tried uninstalling it, downloading it again. Crashes either instantly as soon as I'm in a loading screen, or when I'm in the middle of tasks. Honestly this game ran better before. I could play for hours before it crashed, due to overheating or something. Now I don't even get a chance. I feel like the game is starting to lack optimization. EDIT: Doesn't work now

Overall it's a beautiful game. Main issue for me is the boring (sorry if that sounds rude) story. The games. Is beautiful, but doesn't pull you in. The story makes you want to skip it to get to the beautiful open world and combat. I feel like the story is a afterthought, and it's too much dialogue before you even do any fighting. A lot of talking and no English voice acting so you're reading for long stents of time. Other than that I love it so far.
