I just happened to notice this had been updated in Steam earlier today. The link below shows the full patch notes but here are the major changes:

- Added 5 boss remixes to the game.
- Added 1 new class.
- Added 4 new traits.
- Added 28 new rooms.
- Added ability to reduce shader effect quality for people playing on slower machines.
- Added 6 new Steam achievements (Steam only).

Good on Cellar Door Games for not only continuing to support their game but add free content. This pretty much solidifies my personal Game of the Year choice. I don't have time right now to check it out, but I know what I'm playing tonight.

Oh hey, might check this out. Awesome game.

I really hope that it'll have the extra content when it lands on the Sony-systems. Can't wait to get my hands on it!

I beat the game and quit midway through my NG+ fun game but I can't see me going back soon.

Yes indeedy! I've been purposely dodging this game to grab it for PSFO.

Cool beans!

Hmm, need to go back and finish this sometime.

I maxed everything out on this game and loved it. The patch notes sound like enough to get me to take a peek; especially the new class. Cool.

Sunk 25h in it. Didn't complete NG+. I was trying to get the two last achievements for kicks, but now the bar has been raised and I'm not into completion typically, so this might have the adverse effect.

Noooo, my S-raaaaaaank.

$7.49 on the Humble Store guys...and it comes with a Steam key! I just picked this up. $5 is the cheapest the game has been since release, so I think the current price is a good buy.
