Numbers are neigh impossible to read on low contrast. I have my brightness around 15% and my contrast around 50% - I only turn it up for making graphics. Hit50, hit100 etc. explosions are a bit too dynamic and distract from the focus IMHO. Not only that, but they're pretty big, covering up any underlying hitcircles that may be stacked. The slider pylon is a bit trippy because of how it's animated, and the followcircle is seriously disorienting.
It's not bad by any means - I like it, and the theme. Everything fits. Thing is though, it seems like too much is going on at once despite functioning the exact same as any other skin. It's too busy for my personal taste. I play with it on TWEWY song beatmaps for fun, but I can't play seriously with it - for that, I switch to Xi-Style.
Don't take my personal preference against it.
