Effing zero bombers
I like this track. It did remind me of Castlevania so your inspiration is apparent. All I can suggest for this one is to work on your bass drum a little. Not the heavy one that comes in way late, the one that's in from the beginning. It sounds a little awkward doing it so quickly, try doing one on just the first and second quarter of every measure and adding a delay line to it. You may have already done that, and if that's the case, turn down the feedback a little bit. I also didn't really like the inconsistency of the pattern either, and you never really went anywhere interesting with the heavy bass drum, which was a little disappointing.
I might be more help if I knew what program you used to compose.
This song has a lot of potential, but also a lot to be desired.
Thanks for listening to my tunes, bro,
