==== 你可以先貼 Patch D，確認三條資源跑起來，再貼 Patch E。 ====

===== <syntaxhighlight lang="text">Patch D / Player resources: HULL + ARMOR + FUEL (no art assets) =====

Do NOT change map gen, enemy spawning, exits, or weapon switching.
Only add player resource system and HUD.

1) Add player stats:
* hullMax, hull
* armorMax, armor
* fuelMax, fuel

2) Damage rule:
* On hit, subtract from armor first.
* Overflow damage goes to hull.
* Armor regenerates slowly ONLY when not in combat for X seconds (optional, can skip).
* Hull does NOT regenerate unless you pick an item or upgrade.

3) Fuel rule:
* Fuel drains while moving (or only while boosting if boost exists).
* Fuel regenerates when idle (or always slowly).
* If fuel is 0, movement is allowed but slower OR dash disabled (choose one simple rule).

4) HUD:
* Top-left show 3 bars with numbers:
  HULL: hull/hullMax (red)
  ARMOR: armor/armorMax (blue)
  FUEL: fuel/fuelMax (yellow)

Acceptance:
* Taking damage decreases ARMOR first, then HULL.
* Fuel changes with movement and regen.
* Bars update live and never disappear.

</syntaxhighlight>

===== <syntaxhighlight lang="text">Patch E / Room clear reward: 3-choice upgrade (Isaac style) =====

Do NOT change combat core, rendering, or exits logic besides locking/unlocking.
Add a reward step after enemies cleared.

1) When enemies cleared:
* Unlock exits as usual.
* ALSO spawn an "UPGRADE CONSOLE" panel (center bottom or center screen).

2) Upgrade UI:
* Show 3 cards, choose by keys 1/2/3 (and click).
* Each card displays name + short effect text.

3) Upgrade effects (start simple):
* +10 max HULL and heal +10 hull
* +10 max ARMOR and refill armor to max
* +10 max FUEL and refill fuel to max
(You can randomize 3 from a pool later, but for now fixed is OK.)

4) After choosing:
* Apply upgrade, hide panel, enable exits.

Acceptance:
* Clearing a room always offers 3 upgrades.
* Choosing one applies immediately and exits work.
