Periodic Panic is a small family project: a game about the periodic table, made for two kids who wanted one.
Cellular Pandemic
Cellular Pandemic was designed by Deone and Marvien, on one sheet of paper: the white blood cell and the T cell, the viruses, the four places in the body, and the story. The game was built from their design.
How it is made
Everything is hand-written HTML, CSS and JavaScript. There is no game engine and no framework. Every character, background, explosion and icon is drawn at run time with the Canvas API — there are no image files in the game — and every sound is generated live with the Web Audio API, so there are no audio files either. The whole thing is one page that works offline once installed.

The chemistry
The element facts, the reactions and the uranium-238 decay chain follow the standard published chemistry you would find in any reference table or school text. Any mistake in how they are presented here is ours, not chemistry's — see the terms on how far to trust a game.
Thank you
To Dmitri Mendeleev, who arranged the whole thing in the first place, and to every kid who has ever asked what an element actually is.
