Just finished playing the whole thing. It's actually pretty amazing for an advergame.
I also don't care what anyone says, I actually really like Skrillex. "butt iznt hiz muzk nutin butt wubwubwubwubkrrrrgggjhkjoklhnl?!?!" Not really, there's more to it besides bass wobble and glitch noise, and to someone like me it's really not very cacophonous. (if you want music that really is nothing but cacophony on purpose, listen to Merzbow... old friend of mine tried to get me into that guy, but I couldn't really stand his music, there's not really much substance beyond... cacophony)
I like how the reversed lyrics in Scary Monsters and Nice Sprites was the "you got an item" noise, and the game itself presents a scenario that I think only places like Reboot have ever done before.
