great, but...
This song is 98% awesome! The sound, the chord progressions, the buildup, the little details, sometimes just in the background, simply wonderful stuff! Finest 8-bit epicness!
Now here comes the part where I lack the terminology to exactly describe what is wrong with it. It would be hard for me to write about it in german, even more so in english: well, sometimes your lead melodies are just off. At about 17 seconds into the song the chords go in C major, while that lower lead stays in minor (by playing D#). There are more examples for events like that on the entire song
Now, I'm not sure this is wanted or not. The build up and the excellent and unique choice of chords let me think that you would hear out something like this. But it made the song a little less enjoyable for me. sorry . "just" 9/10 :D
