Interested players can download this game from this site.
Monster XXXperiment is a management style game and there's 3 core resources you have to be aware of.
Researcher Level
Funding
Reputation
Your researcher level dictates how many monster girls and boys you can be in charge of at one time. Every time your researcher level increases you're able to choose a new individual to be in charge of, and you get a burst of funding.
Funding is how much money you have available to you to buy what the individual is requesting. Buying what the individual wants correctly increases the amount of reputation they generate passively for you, however running out of funding can get you in trouble with the site director!
Reputation is generated passively by the individuals. Higher amounts means the research into what they like and dislike is going smoothly. After a certain amount of reputation is gained your Researcher Level will increase!

Role-playing as a Junior Researcher: Users take on the role of a Junior Researcher at NYLIC Laboratories, specializing in studying the likes and dislikes of monster girls and boys, known as "Kins".
Management style gameplay: Users must manage resources, such as researcher level, funding, and reputation, to progress in their career. Increasing researcher level allows for more individuals to be in charge of, while funding is used to purchase desired items and increase reputation.
Point and Click controls: Both mouse and mobile users can easily navigate through the game with simple point and click controls. This intuitive control system makes the game accessible to a wide range of users.
Lewd content customization: Users can choose between two genders for lewd content, which not only affects the sexual content but also changes dialogue. This feature adds a unique level of personalization to the gaming experience.
Diversity of monster girls and boys: The app features a wide variety of monster girls and boys, with different species and subtypes. This means that there is something for everyone, catering to different preferences and ensuring a diverse selection of characters to interact with.
Progression and rewards: As users gain reputation from individuals they study, their researcher level increases, allowing for more choices and greater funding. This progression system provides a sense of achievement and rewards users for their efforts.

Reputation Drives Researcher Growth: Higher reputation signifies smoother research collaboration. Accumulating enough reputation unlocks Researcher Level upgrades, granting access to additional Kins and a sudden funding boost.
Career Progression: From Intern to Renowned Researcher: Climb the ranks at NYLIC Laboratories by mastering resource allocation, expanding your team, and achieving career milestones—your success depends on strategic choices.
Deep Engagement with Unique Characters: Engage with a variety of Kin personalities, each impacting your lab’s reputation differently. Build rapport and foster loyalty through thoughtful research strategies.

Dynamic Game Mechanics & Player Freedom: NYLIC Laboratories offers flexible gameplay, allowing players to experiment with diverse strategies. Explore unconventional approaches to overcome challenges and achieve dominance.
Greetings Everyone! Kaen here.
Monster XXXperiment Classic has been Released!
This is a legacy version of Monster XXXperiment, including all of the versions up until the Last Alpha that was released back in 2023. This is now the defunct Renpy version of the game and will no longer be receiving any updates. We have since moved the game to a new engine to give it a fresh life in the image we want, that still contains the soul that you all came to love and support us and our endeavors for in the first place.
Even though we have had many hardships over the last 2 years, we have stayed here and continued to try to develop the game in the image in our minds. Tech Tsundere and I have been hard at work after meeting to help the game reach the heights and the expectations I'm sure all of you have for it. Thank you for your continued support, and for supporting AstroKaen.

Much better than I expected! The art was great and the writing was better. The characters are cute and I look forward to meeting more of them. The management system is fine when it's working properly, but it's glitchy a lot of the time and sends you into scenes when you aren't ready or expecting it, or loads the wrong background occasionally. But it was never severe or gamebreaking.
more dialogue is needed to make characters feel more involved and to make affection gains less tedious.one mini game per character that builds up affection would also be a solid possibility.characters interacting with other characters would help with immersion.instead of single diet options, having to decide the proportions of meat, fish, and vegetables for a character on a day to day basis would be good. For example, Flare could on some days want 3 portions meat and 2 portions veg out of 5, or pure meat.fulfilling character needs would definitely improve immersion. For example, if a character wanted a specific item, you'd be able to get it and raise affection and maybe unlock an event.sending the girls on activities to boost affection and have events occur would be interesting.
With just a little bit of tweaking and a tad more depth to the management gameplay, Monster XXXperiment could end up being one of my favorite monster girl games of all time! What is here is good stuff and the fact that I want more of it tells you how much I enjoyed it. They have a fun and unique premise here for a game with monster girls and the management gameplay was something that I enjoyed tinkering with. If you like monster girls, be sure to give this game a chance.
