Who asked you to choose this engine over Godot, Unity or Unreal? And why would others make a choice for you? Such a choice would only be up to you based on your own requirements, nobody else can make that choice.

Also this post is really about showing off an engine made in Rust, a "hack" so to speak. You are in Hacker News where people post (usually technical) things that others might find interesting - but not necessarily useful. Consider we get posts about people writing software for retro computers, just for the fun of it.
