 # Tutorial world design
 
-Status: **T1 built** (the Guide, Actions' events, chapter 1 in
-data/tutorial.json, the guide panel and marker); T2-T4 are proposals.
+Status: **T1 and T2 built**: the whole tutorial, on the Valley island
+(seed 1337), with Old Tam the hermit. T3 (its own island) and T4 (hints in
+real worlds) are proposals.
+
+*As built in T2:*
+- All five chapters, 22 steps (data/tutorial.json), in Old Tam's voice:
+  first tools; fire and food (campfire, berries, a roasted mushroom, the
+  diet bars); hunting (workbench, a weapon, a rabbit, butcher and cook,
+  a tip about the other animals); fishing (rod, a catch, grilled); shelter
+  and night (a hut you can stand inside, a bed and spawn, nightfall and a
+  torch, the demo wolf, sleeping).
+- More goals: `any` (club or spear, perch or trout), `shelter`,
+  `bed_spawn`, `demo_wolf`, `continue` (Enter on the reading steps).
+- Step set-ups: the clock jumps to dusk (18:36) and to bedtime (21:00);
+  three rabbits appear 14 m off for the hunt; the demo wolf
+  (scripts/creatures/tutorial_wolf.gd) circles at 11 m for 18 s and slinks
+  off, never biting.
+- Markers for berry bushes, rabbits, the carcass, the lake shore.
+- The tutorial island is calm: no wolf pack, no bear, no thieves.
+- Title screen: **Tutorial** above New World (it says "carry on" once
+  started; with no worlds yet: "New here? Try the tutorial"). Pause menu:
+  Skip this step, Leave the tutorial (saved, carry on later).
+- The end: Old Tam's goodbye card, **Start your own world** (to the New
+  World page) or **Keep exploring**.
+- tests/test_tutorial_full.gd: a bot plays all 22 steps through Actions,
+  in order, to the card. (Bulk materials, like a hut's wood, go straight
+  into its bag; every goal is done as a player does it.)
+- Not yet: a ghost outline for the hut (§2 step 17), sounds for the tick.
 
 *As built in T1:*
 - Actions has signals for what players do: `crafted`, `harvested` (with
