Waltz and Jam: A Ghost, a Puppy and Seven Deadly Sins on 3 December
Flyway Games, a small KRAFTON studio, is about to launch a Zelda-style adventure about a memory-less ghost and his shape-shifting spirit dog. What we know before release, and where to try the demo.
A ghost with no memories wakes up in the afterlife. To move on, he must collect seven stamps and reach the Gate of Judgement. Luckily, he is not alone: a spirit puppy called Jam comes with him. That is the setup of Waltz and Jam, the next game from Flyway Games, which launches on 3 December on PC (Steam), PlayStation 5 and Nintendo Switch 2.
A demo covering roughly the first hour is already on Steam. The price has not yet been revealed.
Two heroes, one set of skills
The hero, Waltz, travels through Downtown, the afterlife realm, guided by a mysterious figure named Low. The game's structure is often compared to The Legend of Zelda: you explore regions, solve puzzles with new tools, and finish each region with a boss fight.
The twist is that the two characters split the abilities between them:
- Jam can transform into a Water Ball or a Trampoline.
- Waltz uses toys left behind by legendary craftsmen as tools.
Combining a dog that turns into a trampoline with a ghost carrying magical toys gives the puzzles a playful, slightly absurd tone, which suits a game about the afterlife that does not want to feel gloomy.
Seven worlds, seven sins
Each of the game's seven worlds takes its inspiration from one of the Seven Deadly Sins, with its own visual concept, puzzles, enemies and bosses. That gives the adventure a clear shape: seven stamps, seven sins, seven very different places to visit.
Who is Flyway Games?
Flyway Games is a wholly owned studio of KRAFTON, founded in 2023. Its previous release was the action roguelike Ascend to ZERO, which launched on Steam and Xbox, including Game Pass. Being part of the company behind PUBG gives it resources most indies lack, but it is still a small team making a compact, personal game, and Waltz and Jam is a very different kind of project from KRAFTON's big online titles.
Where it fits
Waltz and Jam is one of a growing number of Korean games launching on Nintendo Switch 2, which Nintendo released on 5 June 2025. Lizard Smoothie's Shape of Dreams arrived on the console in September 2026 (read its story), and DeerFarm plans a Switch 2 version of Shikhondo: Blue Pieta. For a puzzle adventure about a ghost and his dog, a Nintendo console is a natural home: it is where Zelda-style games have always found their biggest audience.
Launching on three platforms at once is also a sign of confidence. Many small studios start on PC and port later; Flyway Games is going to PC, PlayStation and Nintendo on day one.
Why it matters
Korean studios rarely make Zelda-style adventures, a genre dominated by Japanese and Western developers. WGC's take: Waltz and Jam is interesting precisely because it is not what KRAFTON is known for. If a big Korean company keeps funding small, charming console games like this, the country's indie and mid-sized scene gets a new kind of safety net.
