Once Upon a Shell - about the game

Once Upon a Shell is a roguelike racing game of ridiculous speed and wild upgrades. As a tortoise, use your shell to your advantage and slide downhill to generate speed. Build movement combos between races and prove that even a tortoise can lift The Hare Cup.

Features:

Race at Ridiculous Speeds
Outrun a pack of overconfident hares in chaotic, fast-paced races where momentum is everything.

Master the Shell Slide
Tuck into your shell to drift around the grasslands with ecstatic speed.

Evolve Your Movement
Unlock movement upgrades that influence how you gain speed and how fast you become.

Claim the Hare Cup
Conquer all four divisions in a single run to prove, once and for all, that the tortoise can beat the hares.

A Living Fable
Explore a charming watercolor storybook world that continues the classic tale of The Tortoise and the Hare.
