Neat piece. It almost sounds to me like a side-scrolling stealth game.

I've got suggestions for you to think about if you'd like:

The title you have is quite specific. What is the story behind that?
What kinds of things were you thinking of when you wrote this?
Why did you pick the icon artwork you did?

In my experience, questions like these can be good starting points for being deliberate and intentional in the decisions you make when creating music. I'd be able to give you feedback that is more than just "I like this" or "this isn't for me" if you put some intention behind your music.

That said, for someone who claims to not know what they're doing, I think this is a pretty good shot at a song.

I hope this helps. :)
