Megamix? nice!
Excellent job, this is really one of your highlight songs. Amazingly catchy like all your songs, stayed interesting throughout and your FX were pretty amazing, mix was perfect. The hats in the beat feel a bit generic and just felt like they needed and effect twist but barely noticeable anyways. I liked the piano-like synth at around 1:20, that whole part reminded of that DDR song, castles in the sky.
On a technical level, the quality was excellent and there was no interference or noise and no clipping as far as I could tell.
Melody gets a little repetitive at some points but either way, the things you kept adding covered it up, I was actually looking for the repetition so that's probably why I'm picking on it :p
The ending is really the main part I dont like, I hate anything that ends with a high pass cuz it hurts my poor ears :( a low pass on that part wouldve done wonders especially with the beat IMO
Hmm, I really like this, but because this is a series and there's more to come I'll give this a 9.
Btw, Echos is almost done, one of my best songs yet, I'll pm you when it's done :D
9/10
5/5
