Unfortunately, that may not be the case. Someone shared an Update Plan for last year that Grimhelm released about last year (where he originally planned a v13 release in September), where it showed off some of the animations from this update, plus a few others we haven't seen yet. There will be a male adult alien and a futa chick, from what I remember (the image is in this thread, a few pages back, but I'm lazy and in a hurry), but if you think about it, the game is almost done.
Looking at the items and upgrades, plus objectives, there isn't much left. From here, I'm guessing we tackle whatever the other Quest objective was, then go right after Mother Brain, but there's only 2 colored doors left and 1 upgrade. I'm almost 100% positive that once we get a v14, the first that will happen, is we'll open the door left of the Eve Core and get access to that tiny room, which is likely contain the Orange Key Card, so that shortens things up a bit, unless Grimhelm is going to pull some Castlevania last minute upside down castle bullshit, which I wouldn't be against (space stations are much easier to flip upside down than castles, cause gravity).
However... he is only calling the game v0.13A so far... in theory meaning that the game is barely a tenth of the way done? Maybe lots of DLC?
