Your first 10 seconds are where players decide to stay or bounce. If launch flow drags, you are bleeding retention before gameplay even starts, and every release becomes loading-time firefighting.
You already know the trap: async loading still has an integration phase on the main thread, so the loading screen can look alive while you are still hitting stutter and hitch. If you do not measure from app tap to first interaction, you are guessing and missing the true bottleneck.
The walkthrough profiles a real Android build and exposes the stack: roughly 11 seconds to interactivity on a strong phone, about 8 seconds spent in loading, and a heavy chunk tied to preloading plus audio work. Then one concrete change, moving long clips from Decompress On Load to Streaming, trims around 1.5 seconds in one pass.
Next step: create the empty startup scene, wait 10 seconds, attach the profiler, and capture both main thread and loading thread before changing systems. Then compare audio import settings, scene composition, and background loading priority against a clean baseline.
CEO/Producer translation: each second removed at startup directly reduces retention leak and review tax on every milestone build. Unlock the full Nuke Your Loading Times module now and ship a boot flow that feels instant, not risky.
