Yep, someone on ponychan pointed out the mastering issues and I noticed it as well when I played it on my headphones. I reduced the volume on the vocals and the bassline now. I forgot to double-check it on different sound systems.
About the vocal synching: I've got a very good ear when it comes to synching and rythm and imo it's not off. I think I know what you mean though, the spoken words don't play symultaneously with each kick. Sometimes the vocals start before the pulse/count/kick/whatever you like to call it, but it's supposed to be like that. In the chorus for example: "Luna" kicks in about half a pulse before the meter.
Either way, the synch on the vocals is technically accurate [/twilight-mode]. That's about the only thing I can assure you about this track. XD
