Hole Dweller

This game has taught me some valuable life lessons like: Deforestation gets you hot furry women (and futas) to gobble on your drain pipe, It doesn't matter whats in your pants, you CAN and WILL get pregnant, mining is awesome and children should be sent back to the mines as a form of discipline, Fertility and pregnancy is like gambling you can win small or win big, I somehow got cami pregnant 1 million + times just from 5 minutes in a mating press (atleast theres no child support). Overall this is peak gaming it's very addicting and can be played without sex involved.

Please note that the recommendation of this game is extremely tentative. There is no option for neutral reviews, and I felt like the game did not deserve a "Not Recommended" especially at the extremely reasonable price point.
The good: The game is reasonably engaging, with solid gameplay that feels rewarding. Too many games in the porn game space have gameplay that feels like padding between scenes, but this is has a reasonably entertaining core loop. It feels good to drill, and incrementally improving your team and the area makes for an experience you can lose hours at a stretch with.
Sexual content is varied, and the various other characters have a lot of personality given the constraints in place. They come across as different from each other beyond simply visually.
The bad: Scenes are varied, but repetitive. As long as you can improve the required stats, all scene access is more or less interchangeable across characters, so beyond completionism there's not much reason to focus on more than your core team. The gameplay is easy enough that there's no real need or reason to worry about your team composition or really engage with the skill system in combat beyond the mc's capture ability and its use in buffing your teams stats. The cost of failure is also negligible- you simply stop drilling for the day.
Further, the game has options to set the characters to furry or monstergirl, but (at least in my view) this is more like SUPER FURRY or still pretty furry. Stats also influence the length of the sex scene/minigame in nebulous ways, causing scenes with some characters to last alarmingly short, while with others its excruciatingly long.
If those things seem like deal breakers, I'd suggest giving this game a pass. Otherwise, have fun.

Not the best game to goon to and the the sex is more funny than anything, but it is pretty fun to knock up the bunny with 28 thousand kids at a time.

BUY THIS GAME BEFORE IT GETS BANNED.
Right now, there is a group called Collective Shout that is forcing companies like Steam to remove porno content from their services. If you pay money for game, you should be allowed to play it when ever you want. I am posting this as both a recommendation of the game and a request for others to stand up against censorship.
Seriously, **** Collective Shout.

Definitely says a lot about me owning this game, but I've embraced it.

I like a lot of the action that's going on, a lot of motion .

After Post Nut Clarity , I definitely get bored of it, but its fun to revisit sometimes to fantasize.

To conclude, feeds the fetishes my gosh darn rotted mind desire, but not to worry I have control over most of my actions, this one is intentional.

This game would be addicting even without the porn. Its all about hole. I yearn for the mines, I just wanna DRILL FOR GODS SAKE!!!!!!
The porn is nice though, I like the personalities of all the different characters.

Came for the Impregnation fetish, stayed for the fun gameplay loop.
Its kinda like a non-idle idle clicker with a bit of management sim - pick up ladies, keep them happy by having sex with them (or hooking them up with each other if thats your thing) to unlock rewards. Drill to get resources and currency to buy those rewards. Have kids with the ladies and put them to work for even more resources.
Also, try not to think too hard about the fact you're selling some of your kids off for bonus items at times.
The downsides:
-Documentation is sparse. While the computer has some helpful hints, I still dont understand what a couple of the drill blocks do or which stats to raise if I want to make every one of my girls as big a baby factory as my Kobold Sweetie.
-The Sex minigame can get tedious if you have slow speed and high stamina, but regardless it soon gets too quick to play, leaving you to watch the bar swing back and forth until your stamina runs out.
-The text has a lot of grammar and spelling issues. Luckily this is not a dialogue heavy game, so I can overlook it.
-Fewer sex positions if you play MM/FF and of course cut off from the offspring part of the game unless you buy tons of Robots or have your ladies grow dicks. You can play MF with your PC as the F but I never managed to get her pregnant with more than a dozen kids at a time, so it still handicapped me quite a bit when I tried that way. Basically, the game is heavily weighted for a Male or Herm PC with Female or Herm followers.
-The Tsundere Fox doesn't have a goth skin
Still, the gameplay loop and the fun furry characters are enough to keep me logging back in. Recommended if you want a nice mindless porn game with some compelling not-sex gameplay that you can play one-handed. Be sure to check out the appearance modifying options, each of the girls has some pretty cool alternate skins. Its a shame the Steam workshop didnt take off for this game, the few skins on it are cool and I'd love to see more people porting in their fursonas or new skin styles (Like Goth! Tsundere fox gives off super goth vibes I swear!)
