Anyone heard of this band?

I'm not a huge fan of the 8-bit music scene that's recently popped up in the last 5 - 10 years or so, the majority of songs just don't have enough dynamics backing them.

However, this band has definitely changed my opinion... think along the lines of NES Mega Man music on speed. No vocals, just catchy, speedy, high-pitched melodies.
Their whole album is up for free download, it's rather short:

Not bad stuff. Track 02 "Helix Nebula" definitely stands out from the rest.
