Lily — a faithful native reimplementation of WACCA Reverse (bring your own game files)

v0.2.2 (2026-10-20): a native reimplementation in Rust of the WACCA Reverse (3.07.01) single-player loop, reading charts, music, movies, textures and note meshes from your own game files. Per the README its judgement agrees with the real game on 1,068 of 1,070 measured notes; multiplayer, cards and servers are left out. Builds for Windows and Android; iPad, Linux and macOS build from source. Commits are co-authored by Claude.
