This is a great level and a great use of sampling. The main theme of the level is, of course, a radio. Radios usually play songs that aren't made by them, and I think this level using sampling suits that.

Now, the sampling is done really well. If you didn't know that it samples levels you would probably think that it just references levels, like Viprin said, because everything just fits the song.

Now, the gameplay is really good, and had no problems with it, and has great sync. I loved that robot part with "blind" orbs that are marked by indicators
