This Hand-Drawn Game Lets a Spirit Puppy Become a Trampoline

A dog that turns into a trampoline might be the best pitch in gaming this fall. Korean studio Flyway Games has dated Waltz and Jam, its hand-drawn action-adventure, for December 3, 2026, and the shape-shifting Spirit Puppy at the heart of the game is already stealing the show, according to Hooked Gamers, which covered the announcement this week.

The reveal came during the Triple-i Initiative showcase, where the studio confirmed the adventure will launch simultaneously on Nintendo's newest console, PlayStation 5 and PC via Steam. The bigger surprise was immediate: a playable demo is available on Steam right now, covering roughly the opening hour of the journey. For a holiday season stacked with blockbusters, handing players a free trial on day one of the announcement is a confident move.

You play as Waltz, a ghost who wakes up with no memories in Downtown, a mysterious afterlife. To reach the Gate of Judgement, Waltz must collect seven stamps, guided by an enigmatic figure called Low. Along for the ride is Jam, a loyal spirit puppy who can morph into wonderfully wacky forms: a bouncing water ball that crosses gaps, a springy trampoline that reaches new heights. Waltz, meanwhile, wields toys left behind by legendary craftsmen to unlock new paths and take on enemies in creative ways.

Seven sins, seven handcrafted worlds

The afterlife here is organized around a classic idea. Each of the seven worlds draws inspiration from the Seven Deadly Sins, reimagined as vibrant, fantastical places rather than moral lectures. Expect chaotic restaurants, castles tangled in light and shadow, and deserts that stretch like endless seas. Every realm brings its own visual identity, environmental puzzles, secrets and a formidable boss waiting at the end.

The structure mixes platforming, puzzle-solving and tactical combat, with progression built around the duo's evolving partnership. Jam's transformations are the connective tissue: puzzles and routes are designed around what the puppy can become, while Waltz's gadget-like toys open shortcuts and creative combat options. It is the kind of two-character design that rewards experimentation, and the free demo is the perfect place to test how the pair clicks.

The Spirit Puppy concept also taps into something the industry keeps rediscovering. Animal companions are an instant emotional hook, from loyal horses to talkative sidekicks, and giving the companion shape-shifting powers turns that bond into a gameplay system. If the demo lands, expect Jam to become one of those characters players talk about long after the credits roll.

The indie showcase that keeps delivering

The venue for the announcement matters almost as much as the date. The showcase launched in 2024 as a project of Evil Empire, the developer behind The Rogue Prince of Persia. It runs about forty-five minutes with no host, just a continuous stream of trailers, and previous editions have carried updates for major indie titles including Slay the Spire 2 and Vampire Survivors. This year's edition teased reveals for more than thirty-five games, according to Inven Global.

Flyway itself is a development studio under KRAFTON, the publisher known for backing ambitious projects, which gives the indie release some serious firepower behind the scenes. Day-one launches on three platforms, including Nintendo's newest hardware, signal that this is not a slow-burn festival darling. It is aiming straight at the holiday window, where it will share shelf space with the season's biggest names.

That timing is the gamble and the opportunity. December is crowded, and a hand-drawn adventure has to fight for attention against franchises with marketing budgets in the stratosphere. But the calendar also helps: players are actively hunting for new games, gift cards are in circulation, and a striking art style stands out in a storefront full of photorealistic shooters. The Nintendo's growing game library is still filling out, which gives a distinctive launch an extra edge on the company's newest hardware.

There is also the demo factor. Steam's try-before-you-buy culture has become a genuine discovery engine, and This Is Games SEA notes the demo follows the showcase appearance as a deliberate one-two punch. With demo season in full swing this October, players are already in sampling mode. A free opening hour is the lowest-risk invitation a game can offer, and for a title selling itself on charm, letting the art and the puppy do the talking is smarter than any trailer.

For readers, the move is simple. Download the demo on Steam, play the opening hour, and decide whether the afterlife is worth a December visit. If the full game keeps the demo's promise, the Spirit Puppy and its ghostly best friend could be the sleeper hit of the holiday season.
