Racers & rivals
A large, growing cast of folklore-inspired drivers — heroes, villains, tricksters, and one-line side characters given a second life.
Playable Prototype
GrimmKart
A premium tale-inspired arcade game built around speed, strategy, unlocks, and a huge expandable cast of racers, rivals, karts, companions, pets, skins, and seasonal content.
What GrimmKart is
Folklore, on wheels — built to grow.
GrimmKart is an original Burnt Thumb Works premium game prototype built around speed, strategy, tale-inspired chaos, and a huge expandable cast.
The game pulls from folklore, fairy tales, public-domain story traditions, monsters, tricksters, heroes, villains, side characters, companions, cursed creatures, strange helpers, and the kind of background weirdos who usually get one paragraph before vanishing forever.
GrimmKart is not designed around a tiny fixed roster. It is designed to grow. A hero from one tale, a villain from another, a cursed animal, a forgotten helper, a witch's servant, a talking object, or a background character with one perfect gimmick can all become part of the game — as racers, unlockable skins, companions, pets, rivals, bosses, kart themes, power sets, and seasonal variants.
All designs are original Burnt Thumb Works interpretations rooted in public-domain story traditions — folklore-inspired, not based on any modern franchise.
The expandable roster
One cast, many roles.
Instead of a fixed number of characters or vehicles, GrimmKart is built around an expandable content model.
Karts
Unlockable vehicles with distinct feel and themes, from breadcrumb buggies to cursed coaches.
Companions & pets
Cursed creatures, strange helpers, and talking objects that ride along as collectible companions.
Skins & alternates
Alternate looks and seasonal variants — a way to keep favorites fresh without pay-to-win.
Power sets
Item and ability themes drawn from each tale's logic, so characters play to their story.
Collectible identities
Background weirdos become bosses, rivals, kart themes, or unlockable identities over time.
Premium game direction
A premium game with long-term content support.
The goal is a game that keeps expanding through new seasons, racers, karts, cosmetics, powers, and themed content drops.
Seasonal content vision
Planned seasonal drops and season-pass-style content — new racers, karts, and cosmetics over time. (Planned direction; not live, nothing for sale yet.)
Cosmetic expansion
Planned cosmetic and content expansions — looks and collectibles, never power you have to buy.
Future progression
Planned progression systems, and later, optional online/backend features when they're ready.
Accounts, multiplayer, leaderboards, and any store are future direction — they are not live today. The prototype below is free to play with nothing to buy.
Current public prototype
Playable now, on desktop and mobile.
The current public prototype focuses on making GrimmKart playable online and testing the core feel on desktop and mobile browsers. Two modes ship: a Race Mode across cursed tracks and a Battle Arena Mode for free-drive item combat. No install, no account.
Fresh storybook visual pass
The live build now wears a storybook design pass — candlelit menus, carved fairy-tale panels, flame-lit buttons, and storybook display type — applied across the menus, HUD, and end screens. It's a visual layer only; nothing about how the game plays changed. Fonts are self-hosted, so the look loads without any third-party font service.
Mobile / Android test status
This prototype now includes a rebuilt mobile touch control system: pointer-based buttons that keep working when your thumb slides, support steering and accelerating at the same time, sit clear of the Android browser bar, and can be moved, resized (S/M/L), and reset — your layout is saved on the device. On-screen controls appear automatically on phones and tablets.
