In Heat: Lustful Nights is an adult adventure by MonsterBox, made in Unity with 2D presentation and 3D CG artwork. You play a male employee who takes a job at a workplace where lodging and food seem too good to be true. Each night, you must survive encounters with a dozen threats, with possible rewards if you endure. The game blends furry fantasy horror themes, using animated scenes and adult content.
The current version, v0.6.0.3, was released on October 10, 2026, and development is ongoing. It runs on Windows, Linux, and Mac in English, with no censorship. The latest build adjusts arcade pickup placement, sets Ricotta’s stun cooldown to 20 seconds, and fixes issues with fluid visibility, custom-level token awards, particle orientation, minigame delays, door attacks, and object spawning.
Developer's description
You thought it was a miracle that you landed a job at ██████.
Boarding, food, and all the ██████ you could ever ███. It was just too good to be true!
Unfortunately for you, It was.
Every night you will need to protect yourself from a dozen █████████.
Maybe if you survive, you might just get that ██████.

Up first is our main event for this update: a delightful first date with the Empress of Diamond Straits herself: Nile!
Featuring new animations, new voice lines, and even a couple of new tracks to set the mood, this new date will let you get to know the royal feline like never before, so be sure to check it out, assuming you haven’t stood Sammy up last time. It’s rude to leave one lady waiting; leaving two is a felony.
We’ve also added some new items to the gachapon machine, lovingly crafted by our resident artist, and ready to find their homes in your inventory before being sent off to your favorite girls. There’s some old favorites, and there might be a few surprises that you don’t expect. With enough luck, you might just discover them.
Alongside these content updates, we’ve also improved the graphics quality across all the levels as part of our ongoing quest to make everything the prettiest and smoothest it can be.

Dating
First and foremost,
dates
have arrived on the island.
Go meet with Prinny (who is making her main game debut) and she’ll tell you all about it.
These dates are going to be a mainstay feature of the game moving forward, with many more planned, and another already in development for release with the next update.
Get to know your favorite girls, and enjoy the most quality time you’ve gotten with them so far.
Dates contain a lot of written dialogue and character specific animations, as well as a good number of new voicelines to let their personalities shine.
There’s also some new lewd content (with special content for those who wish to keep things tame.)
Currently, there is only one date available (with Sammy), but more are on their way!
Store
If you’re going to date a lady, you’re going to have to learn how to treat her right.
With this in mind, welcome to the
Store
!
Using tokens that you can find in the Nightclub and Security Office, you can try your luck to secure the gifts that your girls have been waiting for.
This system is still being worked on, so you can’t go full Casanova
just
yet. However, there’s nothing wrong with amassing a little pile of goodies for your favorites.
Oh, and please don’t make fun of me being poor.
Gallery
You’ve been pestering us for it, and here it finally is!
A new gallery has been added, featuring all the animations you know and love, as well as a neat new free-cam that lets you get right where you want to be in the action.
But, if you want to see everything, you’ll have to
play
everything, so be sure to get through the Nightclub and Security Office to unlock all of the animations!
This is a new style of gallery than what we’ve done before, but we’re very happy with it, and hope you all enjoy it as much as we do.
Just don’t hold it against us if you fly right up a character’s nose and they look funny.
The old media gallery still exists, so don’t worry about missing out on all of those animations either, it’s just tucked safely away in the extras menu.
Which leads us into…
Title Screen
Our VCR went to the repair shop and never came back, so welcome to the new title screen and menus for IN HEAT: Lustful Nights!
Due to the sheer number of new systems and menus added in this update, we found it a bit hard getting everything integrated into the old title screen without just throwing everything on the monitor. Therefore we decided to rebuild it from the ground up with ample space should we ever require even more menus!
With new music, new options, and a significant increase in Sammy eye contact, we hope you’ll find this menu to be a bit more responsive than before.
Lighting
Everyone loves lights, and we’re experimenting with some new ones
The game now relies far less on realtime lighting, opting for baked lighting instead. Even Unity was telling us that we were overdoing it before so here we are.
This should generally improve performance and overall just provide more consistent visuals. We’re still testing things out and tweaking some areas, so expect adjustments and even better-looking scenes in the future!
Save Upgrade
Bad news time! Can’t only have good ones
Due to various new systems tracking player progress being added, the savestate of every game will need to be upgraded. Aaaaand this includes a progress reset.
This should however be the first
and
last time we have to do something like this, so that’s good news I guess?
Just to make sure people are aware of this change there’ll be a big spooky disclaimer warning you that your save data will be reset, in case you want to save it beforehand.
Here’s some top secret information for those actually reading this. You can find the savestate under one of the following:

The game is excellent. It's no wonder it won at the Hentai Game Jam or something like that on Itchio. I highly recommend you play it. I myself play the Steam version to support the developers of this incredible work…
