You might want to investigate vopono which allows specific applications to run in a separate network space. This you could for example run Firefox or qbittorrent in a separate virtual network that can only communicate via Mullvad VPN tunnel but not see anything outside it. This is great for desktop use. Another great option is gluetun which allows other docker containers to be bound to a VPN tunnel.

Check out Clonezilla, which is the perfect tool for the job.

Inside and Limbo are great on theck deck. I’ve very much enjoyed Little Nightmares, although checkpoints are sometimes a littler further apart than I’d like. Currently working through Mass Effect which is great but taking up lots of time. With Bastion on sale for $2.99 that’s another very good one.
