⚠️ Warning: This is the legacy documentation for Jumpy, before the Bevy rewrite was merged. It is no longer up-to-date, but it still has some useful thoughts, and some of it may still be good to migrate to the new documentation.

Fish Folk: Jumpy Preview


Fish Folk: Jumpy is a tactical 2D shooter, played by up to 4 players online or on a shared screen. Aim either left or right; the rest is up to clever movement and positioning in this fish-on-fish brawler! For more information about our origin story (Duck Game et.al.) and big-picture plans, see our design document.

Key Features (WIP)

  • 2 to 4 players in either Local Multiplayer or Online Play
  • Easy to pick up, emphasizing strategy over twitch reaction
  • Customize characters with hats, saved to your cross-platform profile
  • Create & explore user-made weapons, levels, audio and other scripted extensions
  • Smart level creation tools
  • Tournaments & matchmaking built in


The game is currently under re-construction as it is being rewritten to use the Bevy game engine. There are now 4 stable maps and 4 items in the new version, and the game is nearly ready for another release.



Anyone involved in the Fish Folk community must follow our code of conduct.
