Never been a huge fan of Cersia levels, but this one definitely stands as the best one i've seen. It just matches the song so well, both in the gameplay, structuring, deco, and pulses. It's really solid overall, it's good at what it does, the effects are really polished and the level is just well crafted. I personally couldn't find anything in particular to really upgrade with the level. However, it's also not outstanding, it plays it safe in a lot of areas, and isn't a level i would find myself rewatching - still really neat though!
