If you love 8-bit sounding music (like that from old school games, but with an updated sound. I guess that is the best way to describe it. It monochromatic sound? Like the old school cellphone ringtones.
It's like a new updated creative version of that super Nintendo Mario music game. You create Sounds that turn into music, there are awesome creations on there. Like Micheal Jackson's beat it, the super Mario theme song, Katy Perry's firework, scooby doo, and many more. Of course without lyrics, just the instrumental sound.
It does take a lot of effort/creativity to make a good island, but if you like to be creative, and make sound/instrumental bit/retro style music. This app is for you.
I believe Google Chrome (on your PC/MAC) has a version of this you can try online (free) go check it out if you have a computer.
Rated 5 stars because it is well put together, good graphics, and I'm sure if it was my type of game, I'd like it.
