I like the sounds themselves, but the arrangement feels quite repetitive.. you add new instruments over time but the flow is still the same, I mean there should be some part with a slightly different rhythm of drums or instruments.. though as a video game loop it would work ok imo
that hihat could be quiter, it overpowers the high frequencies of other stuff
overall it lacks 1.5khz frequencies, making it sound somewhat dull, like I was listening with my ears partly covered
bass feels good, though a bit unstable, try to make everything under c. 150 hz mono and cut everything under 30 hz
keep it up :)
