Hi Kikinaak,
thanks for supporting a good cause and I'm glad you enjoy the game apart from those puzzles. You can quickly cycle through all commands with the TAB key. That makes selecting options/commands a lot faster than typing them in. If you don't like those time-puzzles in general, consider activating the Blind-Friendly Mode, it'll skip those parts of the game (including the hacking game). Once the game has saved, signalized by the little square icon in the bottom right corner, you can restart and continue without the VI mode. Just make sure that "all content hardcore accessibility mode" it set to off in the settings.
I'd love to add a story-mode at some point that skips those parts but we'll see if we find time to implement one.
Hope that helps!
