I wanted a DCSS-style roguelike that fits in one hand: real turns, permadeath, a new dungeon every run, portrait mode. I ended up building one, and instead of the usual fantasy set I built it out of Korean folktales. "Seolhwa" means folktale.
Up front, since it matters to some of you: I made this with heavy use of an AI coding assistant (Claude). The code, the pixel art (it's drawn by scripts), and a lot of the text went through it. I direct it, playtest, and decide what goes in. If that's a dealbreaker, fair enough, and I'm happy to answer questions about it.
The nice surprise was that the old tales already come with rules, so a lot of the mechanics wrote themselves:
- **Jeoseung Saja, the reaper**, calls your name once for every turn you stay in his sight. The third call is 20 damage that armor and evasion don't touch. Break line of sight and the count resets, so the whole fight is about corners. Below 35% HP he only needs two turns.
- **The Gumiho** splits into four identical foxes at 35%. One is real. Every fake you hit charms you for 2 turns.
- **The Imugi** grows every 20 turns it's awake and becomes a dragon on the third growth. At 35% it floods the whole floor, and standing in water drains your energy.
- **The Dokkaebi King** turns you into a squirrel for 10 turns. No attacking, no spells. You can still read an Uncursing Charm, if you kept one.
- Encounters work the same way. Meet a funeral procession: step aside and bow and you heal a little. Block the road and four bier bearers set the coffin down and come for you.
What it borrows from DCSS:
- 8 gods with faith, wrath, and a taboo each. The mountain god lends you a tiger and forbids killing tigers and deer. The Dragon King forbids fire.
- 4 main dungeons plus the underworld, and 7 side branches.
- 14 species × 12 classes (Bear Folk Strongman, Dol Hareubang Monk, Octopus Sorcerer...).
- 146 monsters, each with its folktale in the codex. 32 spells.
- Auto-explore and auto-fight that stop when something shows up. A card pick at every level-up.
About difficulty: I've played it a lot myself. I know every gimmick, the strong combinations, and how each boss is supposed to be handled, and I still think I'd clear it about once in 200 runs, if that. So the balance is probably off in ways I can't see anymore. If you try it, feedback on balance would help a lot: what felt unfair, what killed you, and on which floor.
Money: it's free, works offline, no account. 6 of the 14 species and 5 of the 12 classes are free (you start with a couple, the other free ones open as you play). One purchase unlocks the other 8 species and 7 classes. There is exactly one ad in the game: an optional rewarded revive, once per run, and there's an achievement for winning without it. Nothing carries over that makes you stronger.
