[ANN] Ark.jl: archetype-based entity component system (ECS) for games and simulations

Is Ark.jl version bound to Julia < 1.11? I’m on v1.11.7 and would like to try it out, but got an unsatisfiable package requirements error when installing: restricted by julia compatibility requirements to versions: uninstalled — no versions left

The converse. The registered version has Julia >= 1.12 compat.
The current Project.toml has 1.10 compat though so you should be able to

pkg> add Ark#main

or just use Julia 1.12 with the registered version.
