This one is solid. Really liked it.

Love the syncopated synth, added a lot of character to the whole track. Nice job!

Some parts reminded me of Don't push the button which is cool!

This was really incredible the whole way thru, I liked how kept bringing that piano idea back to center us while developing the rest of the song around it in a way that didn't make it feel boring or too repetitive. The guitar was incredibly well incorporated as well! I felt like despite the intensity of the middle section I was just floating away, in awe of all the cool things I was seeing. Well done!!!

Heh... I love long compositions!

Very nice spacey vibe and.... It's kinda like Black Mesa in some ways, and that's really cool! The synthesizers are a joy)

The transition at 4:10 is cool

The increased dynamics at 4:28 - very motivating to go walk on Mars.

The only thing I can suggest is to improve the overall mixing of the track. Try to give the guitar more space in the sound to make it sound more expressive.
Anyway - nice work)

Woooow, this is GREAT. Yeah I very much get the Half Life feel, as Autumn Spooks mentioned. It actually reminds me of the soundtrack for the remake, Black Mesa, composed by Joel Nielsen; similar vibe for sure.

I think one of my main points of feedback would be it's the drums (particularly the snare ) sound very forward in the mix. I think maybe bringing them back at bit - e.g compressing the attack on the snare - to let some other instruments breathe might work? Particularly from 4:30 onward where there's some beautiful post-rock guitar.

Otherwise I loved it! That short piano motif throughout really anchors the piece :-D I totally get the space-like feel, would be entirely out of place in a game like Destiny.

Great job!!

Really cool track, had a good time listening to it ! Really good fit for space exploration. Maybe a small thing is, I think minimalist long pieces really need to evolve slowly but constantly, and it felt like sometime the music was looping, but really neatpicking here ! Good job !
