I liked this song a bit when I first heard it, but after listening to it while also building a Geometry Dash level with it, I started to not like it as much, and now this constructive criticism review.
If you find this abusive, let me know. I am trying my best to be as constructive as possible.
This song could use better mixing. Like every 5 seconds it repeats the same notes with occasional extra notes which makes it sound very rushed. It's extremely average and too normal with the non-realistic ambience in the background.
The part that saved it is the drop which actually feels intense and it doesn't repeat the same notes with small changes that make it sound rushed. And then it goes back to having the same flaws and gets very repetitive later on. Finally, it ends with some ambience that at first would work for some photography video on YouTube, but it's just out of place and doesn't really make sense for the final notes of this Castle Crashers song.
Overall, it's a pretty good song with a bad execution. I'd low pitch it and add more melodies. This song sounded good to me at first, but I started to realize flaws in it afterwards. Don't take this as harsh! I have very bad music taste and I shun certain songs to prove how awful it is. I still like the drop though so I gave it some points, plus I might have been too harsh.
tl;dr: Try making the song less repetitive and remove some notes. The drop is good though.
