It's sad to see you go from newgrounds, as I only recently started listening to your music. I must ask, does this differ much from the version available on Bandcamp? Is there a bonus track on there or something? If you now don't mind I'll give my thoughts on these.
Sound Of Oblivion - It kind of gives me vibes of a grandious start to something, with the drums sounding like knocks on the door, which then it gets answered with the really well composed guitar. Maybe the oblivion is reffering to not knowing what you're getting into?
Cataclysm - I'm a big fan of the really smooth transition, if You're going to be on a hiatus for now, maybe you could at least release each of these as different tracks on bandcamp? If it goes against your idea for what the EP is then I understand. The composition takes a bit to get's its footing, but not in a bad way, because I entirely try what you were trying to do. I really love the drums and flute, nothing is playing perfectly, each instrument has it's issues, and I don't think that's an issue at all. The more retro sound at 2:17 is just whimsical, it's done really well. I have no real idea for what this could mean, but I wrote what all I could pick up.
Gears and Tears - Whoa the transition once again is really good. This comment is probably, or just most likely not gonna be in any way or form constructive, but I still want to send it the way it is, because I want to give out what I felt during each part. This makes me think of kind of a corruption?
Time N' Space Dilatation - It starts out like an epic, on a high note, after which it gets to the real meat. Once again I'm a big fan of how you wrote all of the parts, the guitar along with the strings sound just amazing.
Death Is The Only Prosperity - I'm out of words , the composition quality is just on another level. The piano sounds amazing, the flute never learned to play perfectly, which definitely adds to the story. It's all really tense and really well executed. I have no way of describing what's going on, yet I at least seem to understand it.
I hope this comment and the way it was written doesn't disturb you or anyone here, since I did seem to go maybe too hard on some places. Hope that it isn't too much of a problem. There's some mysteries in the EP that didn't really get explained, like with the flute, but I do not think it's a problem, quite the opposite. I hope you and anybody's who's listening or reading a good day, and once again sorry if I got too outwards in the comment.
