For a fellow Geometry Dasher, I'll leave a review.
First off I want to say, this was a pleasant surprise! Normally I find songs written by Geometry Dash players to be rather empty and repetitive, with nothing interesting happening. This one, though, is a bit different. While it still may be repetitive, it isn't empty.
Your sound design isn't bad! You know what makes a lead big and strong, as demonstrated by your drops. You also make good use of filters on those sounds for buildup! You have good sweep up sounds, as well, something that a lot of Geometry Dash players lack in their compositions. Not to mention your plucks and pads, as well.
Transitions. Go, you. Your use of transitional elements is fantastic, making different parts of the piece come together as one track perfectly and seamlessly. As that is something I need serious work on, I commend you. Good job! :D
The main melody here is nice. It's really catchy! Hm, I guess that's all there is to say about it, since there only is one melody.
Let's talk about that. Repetition. One thing I feel you need to work on. Repeating the same thing over and over again doesn't cut it. When a song is repetitive, at least for me, I quickly lose interest in it. This is especially so for a song fitting for Geometry Dash, where hearing it over and over again can put it on my "Geometry Dash songs I hate" list due to sheer overuse. I would work on making your tracks with less of the same thing over and over again. Introduce some melodic variation. Do something interesting. I don't know.
Other complaints. You had a nice ending until you decided to put a 5-note pluck riff where it doesn't belong. I think your ending would have been nicer had you omitted that 5-note pluck riff.
Your drums could have used more oomph, especially the kick. Right now they're kind of buried in the mix, which gives your song less power and impact. Also it makes it really hard for me to determine whether or not you side-chained anything, because your kick is nearly inaudible.
I feel like your bassline could have been voiced better. Instead of going up from E to A, you could have gone down to make A -> C less of a jump. Also the high A stands out over all the other notes played by the bass. Your bass sound could also have been louder and more on top of the mix. Bass is important. ;)
I have a feeling you were trying to imitate EnV when you made this. Problem is, copying EnV's style doesn't make your work exactly original. There's nothing that speaks to me as this song being yours more than it being EnV's.
Overall, this is a solid track! You have a nice, catchy melody which sticks to the listener for a long time, and your sounds sound better than that of most Geometry Dash players. However, unoriginality and repetitiveness make your song rather uninteresting in the long run. That being said, I enjoyed your track a lot! 5/5, 9/10, hope this helps!
