Uhh....

The beginning was great. I like how the tension built up.
But suddenly, it went on to some weird bongo beat that didn't match the beginning part at all. In fact, I wouldn't really call this techno.
This song seems to be random song ideas put together. Kind of disorganized, if you asked me.
There's nothing much going on in this song. I think adding more stuff in the background, and not repeating the same melodies over and over again will make this better.

Sorry to be a bit harsh, but this was my honest opinion.
