This is a very good piece of music; it sounds professional. There is a wide variation of ideas throughout the piece, but you manage to keep the theme the same, which is good. It uses a simple 4-chord melody, and the build-up to the drop at 30 seconds works very well. I like how the instrument-heavy section is proceeded by a single-note melody, it introduces the end of the piece nicely. The bassy section at 1 minute sounds great, and if this piece were longer I would have it build up again to another drop.
To conclude, although it is a fairly short piece, it is fun all the way through and isn't repetitive. 5 out of 5

I like the build-up of instruments at the beginning, especially with the electronic 'whizz' sound effect, however I was hoping at about 1 minute through there would be a drop, which there wasn't. In fact, there isn't really a drop throughout the entire piece, which does make it less interesting. Between about 1:00 and 2:25, it is just repetition, with only a couple of melody changes, which is simply boring in my opinion.
However, at around 2:25, you add another single-note melody, which then gets singled out on its own at 2:50, which adds variation and suspense for what comes after. Again, the electronic 'whiz' sounds really cool.
At 3:26, there is a really interesting mix of 2 melodies which both contradict each other. At first, I found it very odd, but after more instruments are added it begins to sound pretty good.
Apart from the last 5 seconds, which is a very satisfying ending by the way, the rest of the piece is just repetition. I think you could have added a new theme here, or ended the piece earlier.
Overall, this is an interesting piece with some great ideas and cool effects, however there is too much repetition. Very decent first creation though. 3 out of 5
