Could you build this?
No Creating a custom 2D Entity Component System (ECS) game engine from scratch in Rust and WGPU targeting WebAssembly demands specialized low-level systems design and modern graphics API mastery.
What it would actually take: The engine requires designing a cache-friendly archetype or sparse-set ECS memory layout in Rust from the ground up, integrated with WGPU abstractions over Vulkan/Metal/DirectX/WebGPU. Hard parts include GPU pipeline management, custom batching 2D renderers, shader writing (WGSL), and cross-compilation quirks on WebAssembly/Safari. It requires a systems engineer proficient in memory safety, data-oriented design, and modern GPU rendering pipelines.
