I would say the story of KH1 is pretty great, it’s just that the gameplay and menus are quite dated and very frustrating to deal with. The platforming is still a bit of a problem but with dual-stick controls it’s at least bearable.
If you don’t want to play it, I would still recommend looking up the story beats in video form so you know the story. KH2 is where I would say the gameplay really takes off.
The -k argument on my openssl accepts a passphrase, not a file. You likely encrypted with the filename as the secret, not it’s contents. Perhaps you should use -kfile instead.
