Feedback
The unchanged 8×12 SD / 32×48 HD projectile files now display on a proportional 6×9 logical canvas. Point collision, 6px/tick speed, 48-tick cadence, 72 damage, ground-only targeting, three-neighbor limit and 16/36px falloff remain unchanged. A real enemy hit shows one compact 16px / 15-tick impact (0.64s) instead of the former 40px / 43-tick ground blast (1.84s); the visual is a contact marker, not a drawn damage-radius boundary. Fire/impact volume is 80/72. Price stays 525,000.
Only declared display sizing, cosmetic hit commands and playback levels/priorities change. No PNG/WAV pixels or samples, equipment icon dimensions, projectile collision rules, damage, cooldown, offsets, targeting, ammunition, capacity, controls or prices are changed. No new muzzle explosion or persistent trail is emitted. Normal original enemy deaths and terrain-destruction effects remain engine-controlled.
The three rapid weapons retain their prior burst/hit counters and reset only their cosmetic tick/projectile gates when mission ticks restart, accepting older saved script state without new fields. This version changes the package save pin; existing pilot compatibility confirmation remains the normal mod mechanism.
Validation and history
See the current Iron Coast retune results and limits. Package-local acceptance reports, validation results and retained test sources describe pre-retune 1.0 behavior unless a result explicitly identifies the newer package and runner. They remain historical material, not current playthrough guarantees.
