I did talk about a potential patch adding the content back on the last page, here's a copy/paste of that post:
It could happen. I haven't deleted the old files containing them, they're just inaccessible within the game right now, and will be eventually replaced with the new assets. If I ever did release a patch, though, it would be after the full game is released; the distinction here is that Patreon does not allow bestiality to be funded using their service, so if the patch is worked on and released after the game comes out and done without using Patreon money, then it's not even breaking any rules, so long as the patch isn't distributed via Patreon.
Like you guessed besspasswrd, creating a patch for every version of the game would simply be too much work. Linking to that sort of thing from Patreon would also break the rules, and because the content would be developed and included alongside the Patreon campaign, there would be no arguing that it was not using Patreon funds, thus my campaign would still be breaking the rules. I can also tell you now the old insects won't be coming back, as I am much more fond of their new design and believe it to be an objective improvement, especially since their animations aren't changing.
To answer your questions xenon - yes, the final game will be sold elsewhere, most likely itch.io and DLsite at least. The game engine I'm using is Game Maker Studio. As for an xray view, I've honestly never thought about it, but I'm willing to consider it at least. It probably wouldn't get added for a while though.
