dama-rb is a 2D game engine that lets you write games in Ruby using a declarative DSL. The engine renders via a Rust/wgpu backend (Metal, Vulkan, DX12, WebGPU), so your game code is pure Ruby while GPU-accelerated graphics run at native speed. Games can run natively or in the browser via ruby.wasm.
