Mario Kart OrigoZ

Three circuits of cheerful arcade kart racing, driven by Mu Mu — the cow — and built around one button.

Play

Press J at the title to open the Controles window, then Comenzar to pick a circuit.

Key	Qué hace
J	Accelerate.
O	Brake — keep holding and you reverse.
A / D	Steer left / right.
K	Hop, drift, and everything that follows from it.
L	Use the item in the slot.

The K button is the game

• Standing still, K is a small straight hop.
• While steering, K is a hop to the opposite side that lands into a drift the way you were turning.
• Hold the drift and the wheel sparks charge: blue at 1 second, orange at 2.5, rainbow at 4. Let go and the colour you were showing pays out 0.5 s / 1.25 s / 2.5 s of boost.
• K off the lip of a ramp spins a trick — nothing happens until you land, and landing it gives 0.75 s of boost.

The three circuits

Circuit	Laps	What it is
Playa Cheep Cheep	4	A sand circuit in a turquoise sea, with Cheep Cheep swimming and leaping beside it.
Pradera Mu Mu	3	A big square dirt route across a meadow — curves, ramps, a shortcut across the middle, cows (one in a sombrero) and wooden windmills.
Senda Arcoiris	4 points	One long rainbow ribbon through space, never revisited: Earth above, stars everywhere, chained balls to dodge, and a finish ringed by heart-shaped clouds.

Off the road

Water slows you 25%, grass slows you 50%, and a boost cancels either for as long as it runs. Senda Arcoiris has no ground at all — fall off and Lakitu lifts you back onto the nearest point of the ribbon.

Items

Every lap has a row of ? crates: a Mushroom (2 s boost) or a Feather (a big jump, and 2 s of boost when you land).

Times

A lap timer with milliseconds runs from the start of the circuit to the finish line, and your best time on each circuit is shown beneath it in the select menu — kept in the world, so it is the same for everyone who plays.

Built in Zero: five slices (kart, tracks, items, screens, audio) around one shared contract, game/core.module, which holds everything the game is made of — the circuits, the feel constants, the surface rules, the boosts, the flow and the records. design/spec.md is the contract, design/references/ the pictures it was built to.
