Stomping was guarded by the invincibility check, so during a downward
dash the player could never deal stomp damage. Move the invincibility
guard to only protect against taking damage, not dealing it.
Extend dash invincibility by PLAYER_DASH_INV_GRACE (0.15s) past the
dash duration so the player is briefly protected after landing.
Closes#15
Turrets now emit orange-white spark particles when taking non-lethal
damage, giving clear visual feedback on hits. On death, turrets get a
dedicated metal explosion effect (shrapnel, hot sparks, flash, smoke)
instead of the generic death puff, with stronger screen shake.
Closes#14
Enemies that fall past the bottom of the level are now instantly destroyed,
preventing them from accumulating off-screen. Cliff detection uses a
speed-scaled lookahead so faster enemies reverse earlier. Charger deals
double damage during charge and knockback scales with the attacker's speed.
Display the player's current score using the font renderer,
right-aligned with an 8px margin from the top-right screen edge.
Closes#5

1. Race condition: session_end now waits for an in-flight
session_start promise before sending, so quick restarts
don't drop the end call.
2. beforeunload: replaced sendBeacon (which can't set headers)
with fetch(..., keepalive: true) so the X-API-Key header
is included and the backend doesn't 401.
3. Stats double-counting: removed stats_record_damage_dealt
and stats_record_kill from damage_entity (which was called
for all damage including player deaths). Now only recorded
at player-sourced call sites (projectile hits, stomps).
4. Removed const-cast: analytics_session_end now takes
GameStats* (non-const) since stats_update_score mutates it.
5. beforeunload now uses stashed stats from the last C-side
session_end call instead of hardcoded zeroes. Session ID is
cleared synchronously before async fetch to prevent races.
6. Removed unused stdint.h include from stats.h.
Implements session-based analytics tracking that sends gameplay
stats to the Horchposten API. Adds stats.{c,h} for accumulating
per-session metrics (kills, deaths, shots, dashes, jumps, pickups,
damage, time) and analytics.{c,h} with EM_JS bridge for fetch()
calls to the backend. Client ID is persisted in localStorage.
Session start/end hooks are wired into all game lifecycle events
(level transitions, restart, quit, tab close via sendBeacon).
Analytics URL/key are configured via data attributes on the canvas
container. Non-WASM builds compile with no-op stubs.

Beam raycast now skips the tile the turret is mounted on, so
wall-embedded laser turrets can shoot outward.
Extract entity_is_enemy() into engine/entity.c as single source
of truth for enemy-type checks. Replaces triplicated type lists
in level.c, drone.c, and projectile.c that caused the collision
bug when new enemy types were added.
All three new entity types were absent from the hardcoded enemy-type
checks in is_enemy() (contact damage + projectile hits), homing
projectile targeting, and drone targeting. Also adds proper death
particle colors for charger (orange) and spawner (purple).
Implement four feature phases:
Phase 1 - Pause menu: extract bitmap font into shared engine/font
module, add MODE_PAUSED with Resume/Restart/Quit overlay.
Phase 2 - Laser turret hazard: ENT_LASER_TURRET with charge/fire/
cooldown state machine, per-pixel beam raycast, two variants (fixed
and tracking). Registered in entity registry with editor icons.
Phase 3 - Charger and Spawner enemies: charger ground patrol with
detect/telegraph/charge/stun cycle (2s charge timeout), spawner that
periodically creates grunts up to a global cap of 3.
Phase 4 - Mars campaign: two handcrafted levels (mars01 surface,
mars02 base), mars_tileset.png, PARALLAX_STYLE_MARS with salmon sky
and red mesas, THEME_MARS_SURFACE/THEME_MARS_BASE for the procedural
generator with per-theme gravity/tileset/parallax. Moon campaign now
chains moon03 -> mars01 -> mars02 -> victory.
Also fix review findings: deterministic seed on generated level
restart, NULL checks on calloc in spawn functions, charge timeout
to prevent infinite charge on flat terrain, and stop suppressing
stderr in Makefile web-serve target so real errors are visible.
Jetpack charges now take 30s to passively recharge (up from 3s),
making fuel management a core gameplay loop. A new fuel canister
powerup (POWERUP_FUEL) restores exactly one charge on pickup.
The existing jetpack powerup remains as the rare full-refill + 15s
boost. Fuel pickups replace most procedural jetpack spawns at higher
spawn rates to compensate for the weaker per-pickup value. Fuel
canisters also appear in corridors and arenas.
Adds orange canister pixel art, editor icon, entity registry entry,
and places fuel pickups throughout moon01.
WIND directive in .lvl files sets a constant horizontal force (px/s^2)
that pushes entities, projectiles, and particles. Positive is rightward.
Wind is applied as acceleration in physics_update() (halved on ground),
directly to projectile and particle velocities, and as a gentle position
drift on flyers. Entities with gravity_scale=0 (drones, spacecraft) are
unaffected. Levels default to no wind when the directive is absent.
Preserve tileset path and parallax style on save instead of
hardcoding tileset.png. Add tileset cycling (T key), tile flag
editing (F key for solid/platform/hazard/none), and 8x8 pixel
mini-icons for all entity types in the palette and canvas.
Fix entity palette not appearing when editor starts without a
prior level load by splitting entity_registry_init into populate
and init phases. Fix bitmap font rendering dropping the top row
by correcting FONT_H from 6 to 7. Widen toolbar button spacing.
Fix invisible collision from placed tiles lacking TileDefs by
calling ensure_tile_def on pencil and fill placement. Fix editor
hotkeys not working in the web build by latching key presses from
SDL_KEYDOWN events instead of comparing keyboard state snapshots.
Raise hard map size cap from 4096 to 8192 via MAX_MAP_SIZE constant.
Replace fixed 16 KB fgets buffer with dynamic line reader that handles
arbitrarily long tile rows. Check calloc returns for tile layer
allocation.
Add entity distance culling: skip updates for entities beyond 2x screen
width from camera, skip rendering beyond 64 px margin. Dead entities
bypass culling so cleanup callbacks always run. Player, spacecraft,
drone, and moving platforms set ENTITY_ALWAYS_UPDATE to opt out.
Replace naive 4-neighbor flood fill with scanline algorithm (O(height)
stack instead of O(area)) for safe use on large maps.
Raise MAX_ENTITY_SPAWNS from 128 to 512 and MAX_EXIT_ZONES from 8 to
16 to support populated large levels.
Spawn an exit ship when the player approaches an exit zone. The ship
flies in, lands near the exit, and waits for the player to board.
On boarding the player is deactivated, the ship takes off, and the
level transition fires after departure.
Distance-based sound effects with stereo panning for explosions, impacts,
and pickups. Spacecraft entity with full state machine (fly-in, land, take
off, fly-out), engine/synth sound loops, thruster particles, and PNG
spritesheet. Moon level intro defers player spawn until ship lands.
Also untrack build/ objects that were committed by mistake.
Introduce moon01.lvl as the starting level — a pure jump-and-run intro
with no gun and no enemies, just platforming over gaps and dodging falling
asteroids. The player picks up their gun upon transitioning to level01.
New features:
- Moon tileset and PARALLAX_STYLE_MOON with crater terrain backgrounds
- Asteroid entity (ENT_ASTEROID): falls from sky, damages on contact,
explodes on ground with particles, respawns after delay
- PLAYER_UNARMED directive disables gun for the level
- Pit rescue mechanic: falling costs 1 HP and auto-dashes upward
- Gun powerup entity type for future armed-pickup levels
- Segment-based procedural level generator with themed rooms
- Extended editor with entity palette and improved tile cycling
- Web shell improvements for Emscripten builds
Implements a full level editor that runs inside the game engine as an
alternative mode, accessible via --edit flag or E key during gameplay.
The editor auto-discovers available tiles from the tileset texture and
entities from a new central registry, so adding new game content
automatically appears in the editor without any editor-specific changes.
Editor features: tile painting (pencil/eraser/flood fill) across 3
layers, entity placement with drag-to-move, player spawn point tool,
camera pan/zoom, grid overlay, .lvl save/load, map resize, and test
play (P to play, ESC to return to editor).
Supporting changes:
- Entity registry centralizes spawn functions (replaces strcmp chain)
- Mouse input + raw keyboard access added to input system
- Camera zoom support for editor overview
- Zoom-aware rendering in tilemap, renderer, and sprite systems
- Powerup and drone sprites/animations wired up (were defined but unused)
- Bitmap font renderer for editor UI (4x6 pixel glyphs, no dependencies)
