Cozy Mall
Cozy Mall is an idle tycoon that plays in the browser. You run a mall drawn like a dollhouse, seen from the side: open shops, level them up, hire staff, build more floors and watch the shoppers ride the escalators.
What you do
- Open shops, level them up and hire staff so the till keeps up with the crowd.
- Build floors and place decor to make the mall nicer and bring in more shoppers.
- Finish missions, spin the lucky wheel, pick a gift, run ad campaigns and send in tour buses for gems and cash.
- For the long game, sell a mall for chain stars (each adds 10% to every sale) and open the next one on a bigger site: Maple Town, Seaside Pier, Downtown and Snowy Peaks.

How it's built
- TypeScript and Vite with the game drawn on an HTML5 canvas. The rules live in a pure, unit-tested core that has no knowledge of the screen.
- It installs like an app and works offline. Progress saves to three slots, and a save code moves a game to another device.
- Built with AI coding agents; the repo carries its own design docs and decision records.
