Almost there, I'm currently playtesting and fixing any bugs I find. It's a lot of stuff so I'm being thorough. It'll have the two new outfits, new bosses, a fourth area, full gallery, rebalancing and more.
I'd like to do one more after this one (the office style map I posted on twitter), but that one should just be the final area and not much else in terms of gameplay changes. As of V3 you'll have about 80-90% of the full release.
