Really like a 'musical alarm'
Though I did notice some shifts as you added and subtracted layers, I did get an overall sense that it was just too repetitive.
It definitely sounds kinda like a musical alarm when it reaches higher pitches and conversely the pounding beats that start 1:10ish make it sound like a club techno piece for a moment.
Parts of this might work for a level in a shooter or action game. Like maybe something thematically similar to Super Metroid's opening or maybe you're escaping from some enemy spaceships?
But as an instrumental song to listen to for enjoyment... it was too repetitive and unsettling for my liking.
Personally, I think you should turn this into a shorter loop, (1 minute-ish) maintaining the theme you dive into at points and maybe reducing the number of quieter moments (like 1:00). Just an idea.
Might be cool as is, but the level'd need to be long to justify this length of a loop.
