Mindustry. It's like Factorio + tower defense. There is a basic campaign and sandbox mode with multiplayer as well. It has in-game visual programming (logic) with which you can do crazy things like play Chess: https://www.youtube.com/watch?v=hoeS3S9S9Dk, and it also has a JavaScript API for mods.
I specifically mentioned torrenting, please re-read. There is no reason to have all the network I/O of your computer go through an extra hop just for one application (e.g. a torrent client) when that application can be configured to use a proxy instead. It increases the network latency, complexity and attack surface of your system.
You can also set a proxy per container (and assign specific websites to always use it), and when you combine that with an ultra-cheap VPS running e.g. a Shadowsocks server you have what I think is the real way to circumvent censorship and bypass regional restrictions (as opposed to using snake oil "VPN" providers or even the Tor Browser).
This is such crap. Modern programming languages (or any other tools) need to be well suited for a specific problem domain, not meet some generalized arbitrary criterion. And modern systems (as in actual low-level software, not web browsers or databases or games) suffer from a severe lack of security and reliability, not performance.
