Test build for #19 (Linux/Wayland startup crash), not a regular release.
Based on 1.5.1 plus one fix: the game now prefers a standard 8-bit display format and skips formats the GPU can't use without extra features (on some Wayland/Vulkan drivers a 16-bit format is listed first, which crashed the game at startup).
Linux only: Birdman64-x86_64.AppImage or birdman64-linux-x64.tar.gz (checksums in SHA256SUMS-linux.txt).
