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.
Level generator: add vertical variety with tall levels (46 tiles).
Segment generators accept ground_row parameter, SEG_CLIMB connects
height zones, transitions inherit predecessor ground row to prevent
walkability gaps. Climb segments respect traversal direction.
Jetpack boost: add blue flame particles during dash (burst + trail)
and continuous idle glow from player back while boost timer is active.
Camera: add 30px vertical look-ahead when player velocity exceeds
50 px/s.
Fix flame vent pedestal in gen_pit to use ground-relative position
instead of map bottom (broken in tall HIGH-zone levels).
Add TigerStyle coding guidelines to AGENTS.md adapted for C11.
Add tall_test.lvl (40x46) for height zone validation.
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.
Expand moon01.lvl from 200 to 1000 tiles using a Python generator
script. The level features 27 gap sections with floating one-way
platforms at varying heights, progressing from easy (8-tile gaps) to
challenging (22-tile gaps with tiny platforms). 20 asteroids spread
across the level. Increase tilemap line buffer from 1024 to 16384
bytes to support wide levels.
Increase base fall speed (120→200), acceleration (200→350), and respawn
delay (3→6s). Add random horizontal drift (±60 px/s) so asteroids fall
at angles. Widen initial stagger (0-3→0-8s). Reduce moon level from 24
asteroids to 8, spread evenly across the level.
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.
