New walker prefab (mushroom_red sprite) patrols a platform, turns at walls and ledges, drains a heart on contact and dies when stomped, bouncing the player up. Three are placed in level2. The level 2 spawn point is set to cell (7,11) so the player starts standing on the floor instead of falling in from mid-air, and level 1's LevelClear now loads level2.tscn.
The three diamonds and both doors were painted as tiles in TerrainBase, which cannot act as pickups or triggers. Replaced them with real prefabs that reuse the same atlas tiles (diamond = (7,3), doors = (10,6) and (11,5)) and erase their placeholder tile on ready. Collecting all three diamonds unlocks the door; touching it fades to black, pauses the tree and shows the level-clear screen with a next-level button (currently reloads the level, as there is only one). HUD now shows the diamond count.
The two new spikes were painted as tiles in TerrainBase, but tileset collision can only make a solid wall, not a damaging hazard. Replaced them with a real spikes_grey prefab that uses the same atlas tile (8,3) plus hazard.gd, and erases the placeholder tile on ready. Also includes the level edits made in the editor (top-left terrain rework).
Player: move/jump (Space), test flight (F, debug builds only). Key: pickup, hold S to aim with live trajectory preview, release to throw, W to warp to the thrown key. Spring bounce. Spikes deal damage. 3-heart health, Z consumes a heal item for +1 heart and a 5s shield. HUD with hearts and item count. Death screen with fade-to-black and restart. Hidden passages. Assets: Kenney Pixel Platformer (CC0).
