I think this loop perfectly fits an old-school video game, so your message is well conveyed. The loop, tough purposefully short, could use more depth in harmony and melody in general. If you wanted to work more with this loop, try making the looping transition more seamless. Perhaps use a percussion fill and quickly break down the loop to the original chords.
I think the piece has great potential. The chords are very soothing, and the percussion is edgy. Good job so far; just keep it up! :D
Please contact me if you would like to use this in a project. We can discuss the details.
