Five seconds to learn, one more round forever
A party game for kids and families that runs in a browser with no install. Run, jump, and bump your friends off a tiny sky arena. The last one standing wins.
The rules had to fit in one sentence, because the players are eight years old and the match starts now.

One room, two homes
The server is authoritative: it runs the match and the clients interpolate between its snapshots, so nobody can cheat by editing their own position.
The whole room logic lives in one core that runs in two places: a Cloudflare Durable Object at the edge, or a plain Node server on a VPS. Same code, same tests.

Keyboard, touch or gamepad. Even in the menus.
Full gamepad support including menus, with button prompts that switch to match the controller you picked up. A touch joystick on phones, automatic low-end graphics on old tablets.
Kids play it, so there is no text or voice chat, there is an age gate and player reports, and an account can be deleted from a page.
$ git log feat(tests): add unit tests for gamepad functionality and profile deletion
