I wanted to make a fun, wholesome experience for our wedding website. Before long, it had turned into Loft Day: a point-and-click browser game with ten rooms, a party, a road trip, and a lot of smaller games, apps, and hidden interactions.

Most of it lives in one 8.8 MB HTML file—roughly 138,000 lines of HTML, SVG, CSS, and JavaScript, with no framework or build step. It also runs a few real runtimes inside the game, including Python through Pyodide, a small Linux system through v86, and, of course, classic shooter games.

I developed it over about a month and 5,700 commits, working with Claude and Codex while directing, testing, and repeatedly changing my mind.

I’d love to hear technical questions, browser reports, and optimization tips for a game of this scale and stack. But first and foremost: wander.
