The Caprini Breeding Program
Visit the planet Caprini, a world with strange biology.
This project is a work in progress. The console will become the basis of a future visual novel. The 'Case Studies' section will be used to show animated webcomics and videos (in the future) pertaining to this world.
This is the fourth installment of a project I started in March 2025 called 'orgasm hell'. I intend to continue that project in this form, with more stories and worldbuilding.
Note: this game is designed to be played on a desktop or phone browser. To adjust the resolution, please simply zoom in/out. Whole numbers (100%, 200%, etc.) preserve the pixel art.

WWooww, this was amazing to play ngl
WOW¡¡¡¡¡¡¡ WOWOWOWOWOW.
The lore and the worldbuilding are something else. And as a biotech I’m genuinely flattered. This plays like a love letter to the most excentric of sciences and beliefs. Your depiction of the use of the eustachian tubes was so unique, I had never thought of how to make skull sex a scientific possibility. And your understanding of cosmology and planetary physics is outstanding.
thank you glad you liked it :) this is my favourite project so I'll continue it for a while
YEEEEESSSSSSSSS; MY PRAYERS¡¡¡¡¡¡¡¡¡ THEY WHERE ANSWERED. ILL SUPORT YOU ON PTRON TILL THE END OF MY DAYS
I almost thought this game was empty, I went into the read me section and noticed that the chapter titles were there, so I assumed that they were just what happened when you clicked them from the console. Perhaps it would be a good idea to have each chapter in the read me link to its chapter in the console, so the read me could be a sort of table of contents. Not bad though, I'd love to see some interactivity in future versions, but this 'tech manual' style has its charms too. Very SCP.
thanks :) good suggestion, I'll add it to the to the next patch, hope to start the interactive story next patch too
Intriguing. Its rare to even have a mention of "unusual head based penetration"
