I love the joyful melody over the heavy drums and synth. It makes a good contrast and the minor notes complement that, making it blend together nicely.
As a song, it feels as if it needs more of a climax to it. Like maybe a growling guitar or anything to break the repetition.
But as a loop it works well. Could listen to it several times and still enjoy it.
I'm just the kind of guy who likes some progressive-ness once in a while, hence the minus half a star.
