The user asked for them to be gone: level 2 was unwinnable and the walkers only added to the frustration. The walker prefab and script stay in the project so they can be placed again later.
Solid bullets were blocking the patrolling enemies, so the field now defaults to solid = false: each bullet is a plain StaticBody2D with no collision layer, plus an Area2D that only detects the player, so nothing is physically obstructed while contact still costs a heart. Ring radii changed from [5, 10, 15] to [3, 6, 9]. Damage is now applied every frame to whatever is overlapping, not only on body_entered, so standing inside a bullet keeps hurting instead of only the first touch. Also picks up the editor change that removed Walker_03.
The user did not want anything firing: the bullets should simply exist in the air as fixed obstacles. bullet_ring (the emitter) is deleted and bullet_field takes its place. bullet_field generates concentric rings of frozen bullets centred on itself, radii given in cells (default 5/10/15), and skips bullets that fall outside the level bounds or land inside solid tiles so nothing is buried in the terrain. Each bullet is a StaticBody2D on the world layer, so it blocks the player and can be stood on; damage defaults to 0 (pure obstacle) and can be raised to turn them into hazards.
walker.gd lost its firing code entirely: monsters now only patrol and hurt on contact, so the only way past is footwork or the key throw + W warp. New bullet_ring prefab fires a set number of bullets evenly spread over a fixed arc on a timer, with directions derived only from its own exports, so every volley is identical and the pattern can be memorised; the level places one at cell (12,12) aimed upward with the 12 bullets spread over 180 degrees. laser.gd gained always_on, defaulting to true, so the five copied lasers are now static hazards that are always lit and damage anything overlapping them rather than blinking on and off. Bullets now stop when they spawn inside terrain.
Removed the stomp-kill from walker.gd: landing on an enemy now just costs a heart like any other contact, so the only way past is to weave through the pattern or use the key throw + W warp. Enemies fire a fan of bullets every fire_interval whose directions are computed only from the facing and the exported spread, never from the player, so every volley traces the identical path and can be memorised. Bullets are code-generated circles (no art needed), die on hitting terrain via a probe raycast, and are freed after their lifetime. New laser prefab cycles wait -> blinking warmup -> firing, and only damages during the firing phase.
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 user will build level 2 by hand in the Godot editor. main.tscn's LevelClear no longer points at a next scene, so the clear button falls back to restarting level 1. The scaffold is still in history at 81ffe98 and can be restored with: git checkout 81ffe98 -- scenes/level_2.tscn
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.
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 key object moved next to the spawn, so the key tile painted at cell (10,8) (on top of the crate tile) was left behind and rendered a second key. Cleared it by setting that record's source_id to -1, which is a same-length edit inside the base64 tile_map_data. Also hurt() no longer teleports to the spawn point, it only drains a heart and grants brief i-frames; only dying returns the player to the spawn.
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).
