The melody beginning at 0:42 - that was what I always thought to be Bionicle's theme. It might not be long but I heard it in the first and in the second flash game and I somehow couldn't forget about it anymore.
+Gunther Matherson Xylophone type thing, string type instrument (violin-ish) played with short strokes, regular synth bass, and it might actually be some form of sax playing the main melody of the song Sheer speculation
