YouTube offered me Bug Fables music as a suggestion.
I can hear the inspiration, but it's not copy/paste, and it's really good (I talk about your music). You've made me want to buy this game :)
As for the music, you've used the motif very well to build your melody. It sticks in your head, it's simple and effective.
Towards the end, when you add all the tracks, it feels like a real climax. The tracks are sufficiently well panned so that every sound can be heard. I just feel there's a bit too much mid and hi. But I could be wrong (mixing and mastering are my Achilles heel).
I'm nitpicking on this point because overall I loved it.
