## 1. Short description
Your lantern is your health bar, and the dark is learning your route. Descend a hand-painted haunted manor, befriend lost spirits and burn oil wisely in a cozy horror roguelite built for 45-minute runs. (202 chars)
## 2. Long description (Steam BBCode)
```
[h2]Your light is your life. The dark is paying attention.[/h2]
Lanternfall is a cozy horror roguelite about carrying one flickering lantern through a manor that rebuilds itself every time you fall. Every flame you spend to see is health you cannot get back.
[h2]Features[/h2]
[list]
[*][b]Oil is light and life.[/b] Burn bright to spot traps and secrets, or dim the flame to stay alive a little longer. Every room asks which risk you prefer.
[*][b]A manor that never repeats.[/b] Rooms rearrange after every death, so a run you lose still teaches you something new about the layout.
[*][b]Befriend the lost.[/b] Gentle spirits wander the halls. Earn their trust and they carry your gear, each with a quirk that changes how you play.
[*][b]Evening-sized runs.[/b] A full descent takes about 45 minutes, so one more try fits before bed.
[*][b]Ink and cello.[/b] Hand-painted ink art and a live cello soundtrack make the dark feel beautiful rather than cruel.
[/list]
[h2]Who it is for[/h2]
If you like the tension of a dungeon crawler with run-based progress but want something moodier and slower than a boss-rush, Lanternfall is a candle-lit evening game. It is spooky, not savage.
[h2]Wishlist Lanternfall[/h2]
Add Lanternfall to your wishlist and the lantern will be waiting.

**Reddit:** Title: I made a roguelite where your lantern oil is your health bar
Body: I wanted a spooky game that fits a single evening. In Lanternfall, brighter light reveals traps but burns your HP, and rooms rearrange after every death. A demo is coming for Next Fest. I would love to hear which risk you would take first.
**TikTok:** Hook: "Imagine if your flashlight was your health bar." Beats: 1) bright flame reveals trap, 2) HP draining, 3) dim flame, shadow close. Caption: One lantern, one manor, one more try. #indiegame #roguelite #cozyhorror
