The Firefly Zero game jam is now official! Build a game for the Firefly Zero handheld game console on the weekend of January 17-19.

Build a game in any of the supported languages: Rust, Go, Lua, Zig, C, C++, TypeScript, AssemblyScript, Elixir, MoonBit

Documentation and SDK’s are available on the website. It’s very easy to get going and no prior experience is necessary.

More information is available on the Itch.io page:

I’ve worked a bit more on my platformer game Blutti for the Firefly Zero. I added a selectable debug level to make it easier to test the game. I also updated the branch with the movement code improvements to the latest version of the code.

The improved movement now supports the different walking speeds, and the jumping is reimplemented with both coyote timing and jump buffering to make the controls a bit easier. Next up is adding back the dash ability, and reimplement conveyor belts and the slippery floor. Those should hopefully be fairly easy to do.

Once that’s done, I can merge the branch back to the main branch. Then I will start on adding some new features.

I received two new PRs with improvements to my platformer game Blutti from @orsinium

I have released version 0.8 which contains these changes:

The movement has been improved to allow both walking and running depending on where on the touchpad you press.

It also now follows the recommended guidelines for which buttons to use.

I received a couple of PR's for my Firefly Zero game Blutt with cleanup and updates needed for the latest version.

The new version is published and available to play now.

⚡️ You can now write games for Firefly Zero in #Zig! Zig is a quirky little language with manual memory management. Safer than C, easier than Rust.

$ firefly_cli new --lang=zig hello-world

I made a quick stop at the Firefly Zero booth to try out the hardware prototype of the console.

New video: a talk from a #golang meetup near Amsterdam. Recorded on 2025-01-16. It covers #WebAssembly, @TinyGo, @mechanoid, @fireflyzero, and a few other cool projects I worked on in 2024.
