<syntaxhighlight lang="text">Patch F / Game Loop Structure: Safe Room -> 10 Rooms -> Boss -> Reward -> Next Difficulty

Do NOT change existing combat mechanics, upgrades, or HUD bars.
Only add stage progression structure and room types.

1) Add progression state:
* sectorLevel (starts at 1)
* stageInSector (starts at 0)
* roomType: SAFE / COMBAT / BOSS

2) On new game start:
* roomType = SAFE
* No enemies spawn, no lockdown.
* Add a "REPAIR STATION": pressing [R] refills HULL/ARMOR/FUEL to max.
* Exits available to start COMBAT loop.

3) Combat loop:
* Entering a COMBAT room: spawn enemies, lockdown until cleared (existing).
* When room cleared:
  stageInSector += 1
  If stageInSector < 10:
    next roomType = COMBAT
  Else (stageInSector == 10):
    next roomType = BOSS

4) Boss room:
* roomType = BOSS
* Spawn 1 boss enemy with large HP and 2 attack patterns (simple is fine).
* Lockdown until boss defeated.

5) Boss reward + difficulty advance:
* After boss defeated, show a reward panel:
* Gain 1 rare weapon (choose from: RAILGUN / PLASMA / BEAM_SABER) OR random one
* Plus a big mech upgrade (3 choices, bigger numbers than normal)
* After choosing reward:
  sectorLevel += 1
  stageInSector = 0
  Load a SAFE room (new sector garage)

6) UI:
* Top-left show:
  SECTOR: sectorLevel
  STAGE: stageInSector / 10
  ROOM: SAFE/COMBAT/BOSS

Acceptance:
* Game always starts in SAFE room with no enemies.
* Clearing 10 combat rooms guarantees a BOSS room.
* Beating boss always gives a rare weapon + big upgrade.
* After boss, sectorLevel increments and player enters SAFE room again.
