not bad
The drum part took alot away from the song... the synths and the frequent changing was pretty good, although I think you strayed a little far from the main tetris melody near the end. This was epic indeed, therefore it should be under trance, not techno. The kick could of been louder in some places and the quality could of used some work. All that aside, everything you did melodically and the large amount of synths you used, were amazing. With a bit of polishing, you could of made this alot better. What you have is a very impressive song tho, good work on it. Go check out some of my songs
