Streamers are sometimes a good way to find indie games. My wife and I watch DieDevDie and he mostly plays stuff from itch.io.
I wasn’t paying super close attention to the puzzle ones, but it happened fairly early in the game.
The document one was only obvious because the streamer reads everything out loud, and he often struggles a bit, and this time the struggle was because of missing words. It’s possible that your brain just filled in the gaps for you.
My wife is watching a streamer play it on easy mode, and even that seems ridiculously hard.
The biggest issue I’ve seen outside of the difficulty level is the Japanese characters in some puzzles aren’t translated, and knowing what they mean is important to solving them.
The translations for documents and such are also pretty bad, often omitting words that are necessary for it to make sense.
Emulation isn’t illegal if you own the game, and even if you don’t they have to prove you never bought it.
The only reason Nintendo could go after the emulators they did was because those companies were charging money for a product using Nintendo’s proprietary encryption key. They can’t touch the open source ones (yet).
