To almost no fanfare, Lisa the Joyful is just out (I seriously stumbled across this by accident while browsing Steam). It's DLC for the base game, at $5. I have no idea how long it is, but hopefully in a day or two I can write down some impressions.

I have only played and hour or so, but I can safely say the soundtrack is still the best video game soundtrack around.

@hott8bitaction: Yeah, so have I, and I agree, the new tracks are great. Good thing they come with the DLC (no extra charge).
The initial twists and turns are so far also pretty great.

Okay this game has some great beats to it. Featuring non-ironic use of an airhorn.

Get HYPE! Can't wait to play it.

@adequatelyprepared: wow that song is really good!

i'm downloading LISA now and i'm real excited to play it

@adequatelyprepared: that is probabaly my favorite track so far. It just hit all the right notes for me especially since I was fighting an enemy at the time.
