Thanks for playing! I hope you all had a scary time. I like how sinister the “You are loved” candle is in this context, right next to the skull

Thanks for boosting this! I’m so glad you enjoyed it. Looking forward to your first issue in May!

What a nice way to close out the year. My story “I Think She Is Starting to Suspect Something” is in the latest issue of Baffling. This one is the result of me spending a lot of time thinking about doppelgängers (and probably honestly from playing a lot of anomaly detection games).

The soundtrack to my Undying Fortress writing sessions In case you want to bring your headphones into the fortress

For anyone who’s interested, I also wrote about the music I listened to while writing Undying Fortress. Spoiler alert: it’s a lot of dungeon synth. open.substack.com/pub/yeonsoon...

Undying Fortress
Undying Fortress YouTube video by Choice of Games

Undying Fortress has been released into the world! During the worst of my long covid I really didn’t think this day would come so this is super surreal for me. It’s been a long, long journey. The game is 40% off until December 25th.

Author Interview: Yeonsoo Julian Kim, “Undying Fortress” Can you and your magic sword save the kingdom from death herself? Infiltrate a tower full of skeletons, decipher its secrets, and escape with your team! Undying Fortress is an interactive dark epic…

My interview about Undying Fortress is now on the Choice of Games blog! This is my second interactive novel with them and it’ll be published on December 19th. I’ve been half-jokingly referring to it as an academic dungeon crawl.

I miss larping with you 😭 I think my dream scenario for our larp reunion would be a gothic freeform larp played by candlelight

Any of you over on Substack? I need to start doing a newsletter or something but I’ve been so unengaged in social media the last few years I have no idea what’s what anymore 😅

I’m so glad to hear that! Teen players have come up with some of the wildest werewolf lore I’ve ever encountered for that game 😂 it’s great to hear more folks are connecting with it, thanks for letting me know!

Send me your best sinus infection + bronchitis remedies. I’m currently sipping on boiled coke with lemon and taking antibiotics the size of horse pills.

I’m running Women Are Werewolves and Pass the Sugar, Please at Big Bad Con and Butternut has eaten a small part of the materials for both games already.

It’s Monday which means it’s time to start asking in advanced: what have we forgotten to pack for Big Bad Con?

Super pumped that my story “Bluebonnet Season” found a home in Neon Hemlock’s The Crawling Moon anthology. This was the last thing I wrote before getting long covid so I’m a bit weirdly emotional about it. www.neonhemlock.com/the-crawling...
