Bloodsport Duel SiMulator: DEMO
A downloadable duel for Windows, macOS, and Linux
In a world where the rich are functionally immortal, Ember signs up for underground duels to the death to make ends meet. As she navigates this cutthroat world of deadly competition between cyborgs, she draws the personal attention of her manager and the league's longtime reigning champion— both individuals who take great delight in the suffering they cause in the arena. Will Ember choose to confront and embrace the cruelty that caused her past relationships to fail, or will she die on her way to becoming the champion?
A Postmortal Figures story, created for the Ryona Yuri VN jam.

actually insane. this is crazy. youre crazy. i cant decide if i need the manager or ember more. god.
i've seen some of your behind-the-scenes snapshots and felt like i was looking at a grad student's thesis article-- finally playing it i see just how much passion and personal love was poured into this (and just a demo alone!!!!) alongside the absolute mastering of the renpy craft. when i first clicked through some stat training i broke out into a huge smile getting to see the little mini embers running, reading, fencing and earning me some points. the detail in the manager's expressions, laughter, AWESOME GLASSES, the animation in the drones and cut-ins, the way the text grabs itself back once the duel begins.... it's just crazy!!!! youre crazy for making this!!!!!!!!!!
i'm so excited to play more, and will wait warmly for future updates!! i did die the first two attempts but with my third being a success i know i'm gonna win it all for sure
Thank you for the kind comment-- It really makes me happy to know that all the time and parts of myself that I put into this game came through.
I'm really excited to see more of this. The manager's so fun with her huge ass grin and shiny red glasses and retro aug fetish. The battle sim is cool and I actually managed to do so bad on one run that I stepped into the ring and immediately fell to the floor and bled out. I couldn't stop laughing. Can't wait to see how this story goes!!
Thank you for your kind words, I look forward to your continued reactions 😊
brutal. cutting. thrilling right 'till the demo's teasing end. will be excitedly awaiting each update with bated breath.
absolutely enamored by the setting, given shape and even a little edge through these bloodsports we find our determined, mysteriously both sadist/maso-motivated mc in. of COURSE this is what the people want - some REAL excitement! what is the point if it doesn't hurt. what's the point indeed!!! each character has their little quips, even that asshole in the sparring room. tch.
highly admire the care given to presentation. obsessed with manager's laugh. loved the training system, fit so very well with this story. in fact, reading devposts then coming to see the system in action - so pleasing!! i will be keeping close eye on this and heartily hope others play soon too.
Thanks for sharing your thoughts and support, I'm happy to hear that you enjoyed this game. 😁 It feels good to know that some of the technical hijinks needed to get character animations to work are appreciated, ahaha.
wowowowow beautiful work! this is going into my wow collection
Thanks for your kind words ☺️
I love how this game vibes with the idea of gladiator fights and also uses an utilitarian style for the ui to idk just push me into the mindset of fighting cog in the murder machine. I was there to die or kill and nothing else mattered. Also I love how everyone is so big in this game, i love big woman, even the manager is hot
another also, damn this game is hard lol, at least for me (but the lack of saves is a good idea, cuz it would be to easy to cheese through!!)
A part of my drive to make this came from the desire to see characters types, builds, and dynamics that I want to see more of. Happy to hear that it landed for you 😌
In the egalitarian future women also get invited to the Kaiji torture nexus for bloodsport. The duel was very disgusting. Awesome
AND women are in managerial positions managing said bloodsports #equality
Glad you enjoyed ^^
this looks so fucking sick, awesome thing to see in my emails today. congrats on the demo release, i will be playing it
Hell yeah! I hope you enjoy it ☺️
manager please put your cigarette out on my face (she ignores me because i have no cybernetics)
I look forward to your reaction to chapter two, once I make it 🤭
agree
