Astra finished in about 1.5 hours with a working but rough engine (basic editor, 3D rendering, physics, scripting, export), while Opus worked for roughly 2.5 days (hitting weekly usage limits) and produced a vastly more polished and feature-complete engine named Bassalt, including a styled editor UI, particle effects, physics joints, post-processing, and even playable Tetris and Marble Run example games. The video is exploratory and anecdotal rather than rigorous benchmarking, and includes a sponsorship segment for a Rust education course. ## Full article daily.dev links to this article rather than hosting it.
