Sounds like a soundtrack. I recon, this might actually be easier to work with inside geometry dash than your songs that were designed specifically for the game. Also the Discord link broke lol.
You are severely underrated! I LOVE this song, It has great mixing, and just is a 10/10 song!
From a first glance, This song is literally Космос but with reverb. from a second glance, it could use more additional sounds. It could really use a bit less reverb in the beginning and just experiment outside of being less ominous Космос. I really like the ominousness of the original, just it's not really enough here. It sounds good though! I did not mean to sound rude so sorry if I sound that way.
the song was intentionally made worse so it would be here.
This song has a very early 2010's feel to it. The guitar is a perfect addition to the song and there's truly nothing negative I can say about it. However, the second half of the song is very hard to make Geometry Dash gameplay to, but aside from that I really enjoy it!
Sounds like a more intense Космос. It's almost like you took the drop and made it the entire song. Very good sounding and would be perfect for if Cherry team decided to make a sequel to that level. Yes I know Penumbra exists, I just don't know if it's a sequel lol.
