Heok! (헉! 오늘도 생존)

Squeeze into a packed Line 2 train at Sindorim before the doors close. Enter your door code at 11:40 PM and hear a voice inside your empty flat ask "Who is it?". Heok! opens one new first-person 3D survival game every day at 6 PM Korea time, each built around a moment most people in Korea have lived through. Runs take 1 to 3 minutes in a PS1-style low-poly look and end with an S to F grade and a national rank, and earlier games stay playable from the weekly schedule. Free on phone or desktop browsers, no install or sign-up. Text is in Korean, but the controls are simple: move, look, and one or two action buttons. Designed and playtested by one person, with code written using AI tools.
