Three full chapters are available to play for free in the game's demo (embedded above). The demo is about an hour of content and is narratively self-contained within its own story arc. If you like it, you can support the game on Patreon or BMT for access to even more chapters!
Story
Just yesterday, you were a human male living in a modern town. Now you’ve found yourself trapped in The Underworld and your body is nothing like it used to be. Who is behind these changes, and how will you change back? The longer you’re down here, the more you start to enjoy your new life…
This is a transformation text adventure with a rich story — it’s already longer than a novel, and continues to develop. You’ll meet a wide cast of characters across the three factions that each have their own ideology about how to deal with people different from themselves. Your actions will determine which faction achieves victory, and by extension, the fate of humans and hybrids alike.

Why can't you make it so that if you have a subscription you can't always use the last paid version if you no longer pay? It should also work with an account if you don't pay, since you no longer have the new updates but can still play the last older version that you paid for when you subscribed?
That's just not a viable business model for a project this niche, sorry.
Is the Whale TF in the demo?
No, demo is the first three chapters (fox, slug/frog, and dragon queen)
How to get the sluggirl transformation
In chapter 2, go to swamp and lose to slug girl (cannot currently be frog)
Game is good but because it's sub based and not a one time pay just like any other game it really push me off since you have to pay 10$ per month if you want to keep having access to the full game.
I click on start game and nothing happens
Is your browser blocking popups? (The game launches into a new tab.)
If that doesn't resolve it, then which browser + device? Supported browsers are Firefox, Chrome, and iOS Safari so one of those should work.
uhhhh normaly not other games like that work
Here is the direct link to the demo
Is there artwork in the paid full version of the game? I've played the demo to death a long time ago and would love to see artwork of certain scenes like the ones on this page.
Not currently, sorry! I have dreams of finishing the character visualizer one day, though. ^.^
Gah. I hate the bmt or whatever it is. I have payed for your game like 5- 6 times through them. And only get a day of play. I gave up about a month ago. Could never express my frustration until here. But I ended up paying like 60-70 bucks for a week of play. And could never get my money back.
Hello, I have just sent an e-mail to the one you registered under regarding this. It looks like you have (at least) two accounts -- very likely you have been logging into one, paying for access, then the next time logging into the other one that you didn't subscribe on. If you reply to my e-mail, I can remove one of them so it is less confusing if you like.
On that note, I don't have any record of you reaching out via e-mail or discord to sort out the issue or alert me to the problem. I am traveling this week for BLFC, but please do reply when you have a chance so we can get it sorted out. It's important to me that players have a good customer experience when purchasing game access and that they're able to get the full month they have paid for.
So there's no real way to get giant junk and use it on people? Just a lot of turning completely female and the various scenes related to such? Doesn't seem like there's much dick wielding content in general.
Not a criticize, more just me wondering since that'd be my primary interest.
Correct, the game is primarily a male to female (w/ vagina) game and is pretty much built around experiencing MtF TF content.
Though if you wear the cock ring, there is some limited support for player as shemale/herm in some chapters, there's not much in the way of content there. Also you can get a horsecock. But most scenes are designed for player as receiver vaginally. That said, if cocked-player content is your main criteria, I don't think I would recommend to purchase access to the game since there's just not that much of player w/ cock content here, IMO. It's definitely MtF focused.
Gotcha, appreciate you responding!
Is there a function to translate languages?
Sorry, there are no translations. I think it is a good idea, but too hard to do. The game has too much text. It would also require a lot of rewrites of existing text and systems to be compatible with translation.
Due to the unusual way to access the game, I feel like you should have disclosed your monetization practices right upfront.
Game access is taken away the moment subscription runs out, meaning you need to keep paying 10/month to retain access, which is kinda frustrating in a platform/environment where people (generally) get to keep what they paid for.
It's literally right there (among other places, also)
Ayee, fair, It's stated in the Patreon page. a few remarks though:
- This game's page currently has no direct link to said patreon (prolly a good idea to include it here)
- Your profile also has no link to Patreon (here would also be fine I suppose, but preferably both spots)
- In your main website, it is indeed stated that it is a subscription, but nowhere directly stated outright that you LOSE access to the game once the sub is up.
As I said before, due to the unusual format - - in a dev-player environment where people are used to keeping what they paid for (even in subscription formats), I feel like it's something you gotta make sure to inform people as explicitly as possible. If it stays sparse/vague like this it's too easy for someone to glance over and feel deceived.
Perhaps you just missed it, but the website does include that same text in multiple places, and most critically, there's no way to subscribe via either payment method without seeing it at least once.
Wat if I just want to pay for the and be a patrion?
Thanks! My Patreon is located here: patreon.com/SkyCorp
i meant wat if i just want pay for the game and not be a patreon?
The game website also includes subscription via BMT if you prefer.
I have a question. Will the free to play or non patrion players get the updates on late basis. Or do ypu need to be a patrion for the full?
No, the demo is just a demo (it doesn't get updated)
So for the full game i need to become a sub?
Yes
On the Wiki is a complete list of the items for full version?
That list is a good start, but it looks like some newer items are missing from that list
Is there a version where you can at least see an image of yourself? I find it difficult to keep track of tf's, especially in the sewers where you can't beat it if you fully turn into a slime
This is something I really want to do actually. I got most of the technical implementation done for a cool character visualizer, but never got real art for it and it kinda stalled out progress-wise. Still something I'd like to do in future though.
The game is pretty good, I just don't know how to download Mod on cell phone and how to make events like egg or inflation or weight gain
Thanks! You have to be a subscriber to use mods, but if you are, then go to the debug rooms and use the mod browser there
Are there no plans for a paid public build when dev is done? The website seems to suggest that it will never be released for non subscribers.
Correct
Played this before the release on itch.io and I am stuck in the game with having some effects after putting on the cursed cockring. Removing a cursed item from you doesn't apparently remove the effects of that cursed item.
What I am trying to ask is: are there going to be a proper walkthrough to this game because there is none from what I noticed and it's very easy to get stuck like I did and not be able to progress any further because you don't know how.
The wiki for this game is dead (and there isn't much information there to begin with) and so is the subreddit and on your Discord there's no walkthroughs.
Hello,
When dealing with cursed items, remember to also drop the item, not only uncurse it.
I was actually looking into getting a forum set up earlier this week to help with gameplay questions. I have not found a forum software I love yet, though.
I have the item dropped, thing is I don't know how to shrink the p*nis so it wouldn't be so big and drag it on the floor so much that it increases tge lust level. I haven't found any device or method that does that or where to go to obtain it. The thing is that if I leave the underground and m*sturb*te in public, my character gets back to the underground.
Also the map in underground is pretty confusing. If you don't play for a while is easy to forget where you're supposed to go or do.
Hope you find a forum software. A walkthrough would be much appreciated. 🙏
Bonerbane should shrink cock size
And more graphics for the map would be cool, it's something an artist friend of mine and I have mused about a bit
in r41.7 is there a way to get past the desert
Chapter 6 lets you go into the desert (it's not intended to go in there before you have a mount.)
Interesting, will it be text only or will it include some animations as in BDCC?
Likely no animations, sorry! Though a (still frame) character visualizer is theoretically possible -- some technical work has been done on it, but no art yet.
👍
