It is a nice, calm song. I like how you applied the 8-bit style to it.
It's just a little too repetitive, though. The main sound of the song doesn't really change. The sounds in the background keep changing, but the main 8 bit sound should've been changed up a little bit at some point in the song.
Sounds really up beat, but at the same time calm. I love it :)
Please contact me if you would like to use this in a project. We can discuss the details.
