The mobile game CUE! -See You Everyday- announced its closure schedule on Feb. 27 2021 (Official Website, Twitter). Service will be ended on 12:00 PM JST @ Apr. 30 2021 and the game will not be accessible afterwards.

Considering the game is heavily story-focused, archiving the game assets will help players get an idea of its core content, and possibly even a fan revival project, considering the scripting was mostly in very readable JSON.

Workflow

Basic datamining reveals plain text assets crimoviemanifest and crisoundmanifest, apparently file lists for CriWare ADX 2 and Sofdec;
Set up MiTMProxy, intercept and analyze traffic;
CDN base address revealed to be https://cdn.cue-liber.jp/; request for master file list CustomiOSManifest.gz / CustomAndroidManifest.gz intercepted;
Non-Criware assets seem to have a hash attached to the file names, IL2CPP reverse-engineering reveals the algorithm to be Unity's Hash128() (Sagilio);
Datamine previously intercepted master file lists (gdzhong);
Populate URL lists with rules (Hash128 suffixes to Unity assets, none to Cri ones) (gdzhong);
Test the URL lists while crawling the CDN; filter out 404s and recheck link for fixing;
URL list fixing & integration.
