The island map

Each subject is an island in a ring, seen straight on, with open space between them and dotted routes between subjects that share ideas. The map starts in evening light, and a hall turns to day colour when its ideas are learned. Point at a building to see its name.

Background:

Physics: all 3 games learned. You won one idea back along the way.

What this sketch is, and is not

The islands are the same 3D map, seen straight on, drawn once at evening and once in daylight from the games' own props. Both cost nothing to make. A lit hall shows the daylight picture on its own pad and buildings.
The islands sit in a ring around Biology (Emily's pick over two rows). Each island is one layer with one soft shadow.
The colour behind the islands is the page's own, so three light grounds can be compared without redrawing: Mist, Linen and Driftwood.
Only the seven subjects carry a label; a hall's name shows when you point at it, tap it or reach it with Tab. At 100 games, tapping an island would open it.
The bridge between Biology and Chemistry is an example: one brick for each idea both islands use, four here. The real number for each pair of islands gets counted once every game names its ideas with the same kind of id. A whole bridge lights its lamps in the evening.
Which subjects share ideas is my first placement (Math beside Physics and beside Individuals and societies; Chemistry beside Biology and Earth science). It needs your check, and later the real links between ideas.
The question is the friction question from Newton's first game, word for word, with its own explanations for each wrong answer.
“Your map” reads this browser’s own record, the one every game keeps (learn-record.js) and the review clock (review.js): a hall turns to day colour when one of its ideas is learned, its lamp goes amber when that idea is due again, the gold path shows the halls you played in the order you first played them, and a change plays once, the first time the map sees it. “A learner’s story” is a made-up learner, to show what lies ahead.
Only Newton 1 can be played from this page. The bridge is left out of “Your map” until the shared ideas between islands are counted.
In the story, lights change only when an idea is learned or due again.
Nothing moves on a loop. The coral dashes drift three times and stop.
Sound starts off. When it is on, a short chime plays after a right answer and a chord on opening night; here they are simple tones, not the final sounds.
Left for later: the landmark on a finished island, water along a route when two subjects are linked (it waits for real links), the zoom into one island, the phone layout.
