About this game

Welcome to Hinsdale Days by HinsdaleDays, an HTML sandbox dating sim set at a sleepy New England university. You're a transfer student starting your first day, tasked with exploring campus, befriending students, and stacking up romantic threads across a full academic year.

The school setting anchors seven women with lengthy storylines - multi-month narrative arcs ranging from rewriting century-old historical documents to joining the campus play to navigating dating-app misfires - plus around a dozen lighter side romances. Branching choices and a New Game Plus mode make replays land differently each time.

Expect mind control, BDSM, blackmail, corruption, drugs, sleep sex and slave routes among the heavier kinks, paired with the lighter romance + harem beats that the social calendar layers in throughout the year.

Changelog

Update
ROADMAP: Onwards: New job at the Student Affairs Office, with two new girls who will have a significant amount of content (Allegra and Riley). Will more content than most other side paths (e.g. Meyerhold, Sophia's arc, etc.)
v1.3
(Current Version) Major Update: Added Abby's ending. This is a very lengthy sequence that has multiple endings, paths, and unique events. The Domme (Brat) and Sub (Tamed) paths are equal in length. There are three endings for each path, making six in all. In all, there are 420 images in the entire ending sequence, with 210 anime images and 210 real-life images. For reference of the scale of this: there are 316 scene images in the "base" game, with all the sex scenes, PicFeed posts, and so on. So yes, it's a lot of new content! Added the passage teleporter in the Debug section in Settings. This will let the player input the name of a passage and teleport there. Want to start Abby's endings right away? Use these passage names: Abby Tutorial Sub (for her tamed/sub ending) and Abby Tutorial Dom (for her brat/domme ending) Changed Abby's real-life headshots (normal, brat, tamed) Replaced Abby's chastity anal scene image with a better one (in my opinion, at least)
v1.26
Added the Hinsdale Corruption Awareness Society posters. These will be visible around campus if (and only if!) you have gained the ability to see real-life versions of headshots (done through brewing the Elixir of True Sight). Want to just see it and not deal with that? Go to the Debug area in Settings and turn the variable "glasses" from false to true. These posters will only appear if you have the real-life art option on -- you can swap the art style by clicking a headshot, going between anime and real-life. Added a couple of emails that explain this "Hinsdale Corruption Awareness Society" a bit. Added three new PicFeed posts for each of Fiona's endings in the Revenge path. Added a new PicFeed post that foreshadows upcoming content for the Student Affairs Office. Added the Student Affairs Office to the map. Content is still being built, but you can familiarize yourself with the new location and its future characters until the content is finished. Fixed recurring bug of hacked photos not appearing when you are on web mode. Minor bug fixes and typos
v1.25
Added an "Easy Mode" for Fiona's Chemical Warfare sequence. You can switch it on under the expandable/collapsible header, and from there, increase and decrease the three core values of the minigame (Willpower, Resistance, Suspicion). Added Autosave feature. This will automatically save the most recent turn. This won't help against running into bugs, but will keep your most recent turn in case you accidentally close the game or forget to manually save. Added "Text Only Mode" for those who really, really do not like the AI art in this game. There will almost certainly be small bugs and issues with images still popping up; flag these to me in the Discord, please! Added a Debug Room to the Settings menu. This will let you do quick modifications to variables if you know their name, so as not to rely on a third-party Twine save editor. Also, you could use this to cheat, if you really want. Made slight modifications to Daisy's first passage in the tutorial, allowing the user to switch Online vs. Local images, and Text-Only Mode.
v1.24
Added an experimental feature: dynamic responses via AI LLMs. You can enable this through your Settings page, and then interact with Maya's livechat. This may be implemented in other areas later in the game, but for now, it's just in Maya's livechat. Updated the Advanced Help section to answer some commonly asked questions. Typos and small bug fixes
v1.23
Added three new erotica stories for Daisy. You can access these in her room in the erotica section. The three new stories are unlocked for Sophia (once you finish her arc), Chloe (once you finish her arc after meeting her on Sparkr), and Fiona's Revenge Arc (once you have finished that in a New Game+). Typos and small bug fixes
Installation
1. Extract and run. Or use Itch.io. You can figure it out.

2. You can run just the index.html file.
Developer Notes
This game is totally, completely, fully completed and ready to go. I developed this game because, in short, I got bored of the available Twine/HTML games out there. There are way too many unfinished, buggy, hideous HTML games, and I tried to avoid a lot of the traps you see out there in these games. There are no hideous real-life porn clips with giant watermarks on them. There won’t be egregious spelling errors or bugs – but typos, despite a extensive playtesting, still likely exist. You won’t be starting off in your step-mother’s house and spying on your sister in the shower.

There is approximately 15-20 hours of content here, as long as you don’t speed-click through the text as fast as you can. The gameplay is basically a mix of Degrees of Lewdity, Course of Temptation, and Love & Sex: Second Base, with a dash of Star Knightess Aura and Third Crisis. I took out most all of the life sim elements (e.g. finding food, using the bathroom, etc.) of the aforementioned HTML games, and lean heavier into branching choices and a wide range of fetish content. There is a New Game+ mode, and the game was built with the hope that the player will do this at least once, with some fun easter eggs, hidden content, branching choices, etc. to keep things from getting repetitive.

Twine tells me that the game has 741,383 words (this obviously includes all the code, not just output text you see) and over 2,900 passages to it. So it’s not small, for whatever those numbers are worth

Lastly, I’ll discuss the biggest weakness of my game: I used AI for some visual design elements, and to create images. A lot of them. In fact, all of the images you’ll find in the /img/ folder except a random black box or two. I decided between going for a pure, 100% text game (similar to Course of Temptation or Degrees of Lewdity minus the pixel sprites/map), or to include AI images to complement the rest of the game. I went with the latter option, despite my better judgment. I hate AI as much as anyone – if given the chance, I’d happily shoot Sam Altman into the sun, do [redacted] acts against data centers, etc. But, well, my budget for this game was the time value of hundreds upon hundreds of hours I spent on it, and whatever my extra electricity bill was from running a thousand ComfyUI prompts. So that doesn’t involve any money to pay an artist to draw hundreds of images.

I did my very best to make sure the characters portraits are consistent between scenes, the images are used when needed and not excessively, and look “natural” within the game with their style (a sort of Persona 5-esque styling). They are not perfect. The backgrounds are not as consistent as I wish they could be, and sometimes character eye color changes a slight shade or two, such as from a cornflower blue to a baby blue. So it goes. I also used some AI for tinkering with some visual design elements with the page styling stuff, as I don’t have much of a natural eye for these things.

So, I hope you enjoy the game. I’ve spent the better part of the year spending way too much of my free time on this, and held off on any 0.0.1 junk releases, so I could drop it all at once in a fully playable state.

Enjoy!

NOTE: This game is playable, but not fully, 100% functional on mobile when you play on the Itch.io browser. That said, I meant for it to be played on an actual computer or tablet, or anything else with a decent resolution.
