Blouma remake for Android – playtest build (the whole public demo)
====================================================================

Phones: Android 11 or newer, 64-bit ARM (arm64-v8a). Tested so far only without a phone
(see docs/android.md in the repository); please report what you see.

Install (sideload)
------------------
Either
  a) copy blouma-<date>.apk to the phone (USB, cloud, mail ...), open it in the Files app
     and allow "Install unknown apps" for that app when Android asks; or
  b) with adb: adb install -r blouma-<date>.apk
Updates install over the old version and keep the saves, as long as they are signed with
the same key (all builds from tools/build_android.sh are). The first start unpacks the
game data (~77 MB) once – a few seconds of black screen.

Controls
--------
The picture is shown pixel-perfect (integer scale, e.g. 3x on 1600x720, 5x on 2400x1080);
the buttons sit in the black strips left and right of it, never over the picture.

  left strip:   F1  F2  KEYS        right strip:   R  ENTER
                                                   ALT   TAB
                (d-pad: arrows)                    CTRL  SPACE

  * d-pad: slide your thumb; diagonals give two arrows (e.g. LEFT+UP).
  * use both thumbs at once: d-pad + CTRL = run, UP + CTRL etc.
  * touch the picture = mouse click: title bar (menus), inventory, LIVES, menu choices,
    YES/NO.
  * KEYS switches both strips to the rarer keys (1-7, BKSP, PGUP/PGDN/END, ENTER, F11/F12,
    H, and the letters Y N Z C L O Q E T S I W D F R, TAB) and back.
  * F1 = menu 1 (L load, O game over, Q quit); F2 = menu 2 (T setup, S save, I info).
  * Android Back (button or edge swipe) = F1: it opens the game's menu instead of quitting
    (the original quits at once on Esc). Quit with Q in that menu, or just leave the app.
  * Hardware keyboard: works like on the PC (Esc = F1 menu, see above). The touch
    buttons hide while you type and come back on the next touch.
  * Gamepad: d-pad = arrows, A = CTRL, B = ALT, X = SPACE, Y = TAB, L1 = R, R1 = ENTER,
    START = F1, SELECT = F2.

The game pauses (with sound) when you switch to another app and continues when you come
back. Saves stay in the app's storage (deleted when the app is uninstalled).
