level_clear.gd gained a next_level_scene export: empty reloads the current level, otherwise it changes to the given scene. Level 1 now points at res://scenes/level_2.tscn. level_2.tscn is an empty but complete level: background, three TileMapLayers wired to the same TileSet, player, HUD, death screen and level-clear screen, plus the empty prefab containers. Its hidden_passages script explicitly sets hidden_cells = [] so level 1's passage cells are not carved here.

## 显示时把整棵树暂停，所以这一层的 process_mode 设成 ALWAYS（见 .tscn），
