# OpenInsaniquarium: reimplementing Insaniquarium Deluxe

> OpenInsaniquarium reimplements Insaniquarium Deluxe 1.1 in Rust with a deterministic simulation and Bevy presentation layer. It loads assets from the user's game installation and uses captured original-game traces for tick-by-tick comparisons; the author reports that the preview covers Adventure's first tank and all 24 pets in testing.
