I really like the artwork of this. But honestly - i don't like it how musicians are animated. This is some kind of 8-bit-ish music and the drummer/guitarist etc. does nothing but rock on their instrument. Especially the drummer does nonsense stuff. As a musician, i feel very uncomfortable watching this. As i do watching many other cartoons/animation doing the same (because the author doesn't have a clue how instruments work, i guess). Tom and Jerry did this very well imo. But this.. i do not like.

Very good work at 0:52ish, snare / tom video sync.
Great.

Nice animation!
Constructive Critisism part:
Though i didn't like the music transition at 1:15. It really didn't merge over or whatsoever, it seems like you didn't even make a cross fade or something like that. Also the White Noise at 1:37 killed my ears and the explosions were also too loud (i could hear this crackle sound).

where can i get the music from the first level/stage?

balancing issues!

from wave ~6-10 it was damn hard! after wave 15 it was easy as a pie, bossfight was awesome

titanomachina!

look you can see the titanomachina before the title screen!
titanomachinima was posted way after this submission! awesome

The production quality is top notch. Keep on making dem tracks!

Good ideas, but i think you need more work on that drop :) sounds a little overpresent at ~0:55, but the idea is great.

Looks a little chubby but it's great! I really like the composition of the colours
