Slay the Spore

What it is

Slay the Spore is a browser game about evolving creatures, made by @op__nico for Vibe Jam 2026. The author's one-line pitch on the jam page is "Slay the Spire meets Spore," blending a deck-building climber with a creature-evolution game. The home screen offers Play Game, Multiplayer and an Evolution Lab. What sets it apart is that it puts two very different kinds of play together. The jam rules require at least 90% of the code to be written by AI; the jam page doesn't list which AI tools were used.

Who it's for: players who enjoy deck-building and evolving their creatures.

Before you start: under Vibe Jam's rules it's free to play in the browser with no sign-up. The pages are in English, and mobile support isn't stated. Multiplayer goes online. It is an independent game with no connection to the makers of Slay the Spire or Spore. No age rating is given.
