Frequently Asked Questions
What is Jumpy?
Jumpy is a tactical 2D arena shooter — think tight platforming plus one-hit-pressure gunfights — developed in the open by the Fish Folk collective using the Rust programming language and the Bevy game engine. The developers publish an official WebAssembly build of the game, which is what this page embeds, unmodified.
Why does the page say Chrome is recommended?
WebAssembly games this size benefit from Chrome-family browsers’ wasm and input handling; the Fish Folk demo notes best performance there. It runs in Firefox and Safari too — if you hit slowdowns, try a Chromium browser.
Can I play with a friend?
Yes — Jumpy supports local multiplayer in the same tab (one keyboard or attached gamepads), which makes it a great couch arena game. There is also bot play for solo practice.
Is it finished?
Jumpy is actively developed — playable today with polished core combat, while new content and balancing continue in the open on GitHub. The embedded demo always tracks the team’s latest official release.
