Sorry. It's just that it's in 3D, so maybe your computer isn't powerful enough (and even if it is, it's just that loading a game like this in a browser is more resource-intensive, and it uses WebAssembly, or WASM for short), and it was made in Godot :)
I get you, but browser loading is just built different (and slower). Loading assets through a browser is a whole different beast than running a native executable. WebGL and WASM have to translate everything, which bottlenecks the process regardless of your PC specs. Even a supercomputer struggles with browser-based 3D sometimes! Just download the version for your OS; it'll probably run at a super smooth framerate. Let the egg fly! 🥚:D
