==== 下面這段就是你要的「修補種子」。它會把整個遊戲從橫向卷軸改成 Isaac-style 房間 roguelite，而且順便把貼紙素材問題、AI跳躍問題、Boss砲台問題一起處理掉。 ====

<syntaxhighlight lang="text">Patch / Change Request:

Change request:
* Change the game from side-scrolling platformer to an Isaac-like room-based roguelite.
* Each room is a fixed-size arena (no platform pits). Doors connect to up/down/left/right neighboring rooms.
* Enter a room -> spawn random enemies -> clear all -> reward -> choose next room.
* After clearing 5 normal rooms, the next room is a Boss room. Then loop infinitely with increasing difficulty (tier++).

Room generation:
* Generate a grid-based map around the start room. Use procedural generation to create connected rooms (roguelite).
* Reveal only visited rooms; show a minimap with current room highlighted.
* Each room has a type and reward:
* Combat, Elite, Shop, Repair, Treasure, Boss.
* When clearing a room, show reward choice UI:
* +Energy Max (fuel tank)
* +HP/Armor Max
* Weapon upgrade
* Credits
* Shop room: allow buying repairs, new weapons, and modules (laser gun, plasma sword, homing missile, etc).

Gameplay adjustments (to address previous issues):
* Remove platform jump dependency. Keep movement as top-down / twin-stick or arena shooter style inside rooms.
* Enemy AI must not rely on jumping. Use dash/leap ability if needed (short burst movement).
* Boss must have multiple phases and mobility/attacks (not a stationary turret). Include at least 3 phases with patterns.

Art / visual constraint fix:
* Do NOT rely on transparent PNG assets. Use Canvas drawing (pixel-like rectangles/sprites) with consistent outlines.
* Use a 64-bit pixel style: chunky pixels, crisp edges, visible outlines.
* Minimal VFX: small pixel sparks, subtle screen shake, avoid glow.

Do not change:
* Theme: hard-boiled corporate mech mercenary scavenging forbidden tech in wasteland.
* Stats: HP, Armor, Energy (fuel).
* Upgrades economy and mercenary tone (terse UI text).

Acceptance criteria:
* Player can clear rooms, choose next room via doors, receive upgrades/loot, visit shop, and fight a boss after 5 rooms.
* Difficulty scales over time and the loop can continue indefinitely.
* No exploit where enemies get stuck due to terrain; rooms are arenas with simple obstacles (cover) only.
