Are games actually harder to write in Rust?

I've been using bevy for a week and it's honestly been a breeze. I've had to use unsafecell only once for multithreading in my 2d map generator. Other than that, it's only been enforcing good practices like using queues instead of directly mutating other objects.

I don't know why people say it's harder in Rust. It's far better than using C++, especially for what long term projects end up becoming. You avoid so many side effects.
