Possible disadvantages

    The audio capabilities of WASM-4 are fairly basic, which can be restrictive for developers looking to create rich soundscapes or complex music tracks.

    WASM-4 does not come with a dedicated development environment, which means that developers have to set up their own toolchains and workflows.

    Due to its focus on simplicity and retro-style games, the engine may not support highly complex game mechanics or large-scale games.
  • Dependence on WebAssembly
    Relying on WebAssembly means that WASM-4 is dependent on browser support for new features, which may lag behind native game development platforms.
