Took a couple of weeks to finish this, and it was indeed a fun project. I'm a gamer, and being a big Nintendo fan, I was inspired to do an arrangement of this. I started it without much of an idea of what direction I would go with it, but after writing the first few phrases I played around with the samples and the tempo a bit and decided it would sound like it does now.
I actually almost lost the project file because the motherboard of the PC I wrote this on died after a sudden power surge. So I went through a lot of work to retrieve the hard drive from that computer and copy everything to my external hard drive.
