Korean developer Flyway Games announced at the Triple-i Initiative that Waltz and Jam, its hand-drawn action-adventure platformer, launches on December 3, 2026 for Nintendo Switch 2, PlayStation 5 and PC via Steam. A free demo also surprise-launched on Steam.

A ghost, a puppy and seven sins

Waltz wakes with no memory in Downtown, a mysterious afterlife where he must collect seven stamps to reach the Gate of Judgement. Guided by the enigmatic Low and joined by Jam, his loyal spirit puppy, he journeys through seven handcrafted worlds, each inspired by one of the Seven Deadly Sins, from chaotic restaurants to castles of light and shadow and deserts like endless seas. Each realm has secrets, puzzles, enemies and a boss.

The duo grows together: Jam transforms into wacky forms like a Water Ball that crosses gaps and a springy Trampoline that reaches new heights, while Waltz uses toys left by legendary craftsmen to open paths and tackle enemies.
