Here are related comments from Steam and elsewhere:
"Sometimes I would have appreciated more feedback from the protagonist because sometimes it's not clear why some actions don't work (I don't want to spoil, but it concerns a little boat)."
"But the puzzle design is very bad
puzzles are too obscure, and the game system lacks hints. If you don't do exactly what the game expects you to do you just get generic answers from the environment. Then all the fun fades out because it just gets to the point of you trying every item with every other item or environment object to find the solution."
"lacks guidance and feedback, making it more frustrating than it needs to be."
"Lazy English translation, unbalanced puzzles, no voice actors. So much of it was right and I tried to enjoy it, but the nonsense puzzle solutions were what ruined it for me"
"Actually I would be very surprised if most people managed to beat it without hints."
"There isn't enough feedback when trying different interactions. For instance, when I try to grab the paper boat from the canal, the protagonist says, 'Can't reach it with my hands.' Huh? It looks like she could just reach over the canal wall and grab the boat, but whatever. So I try to snag the boat with the long poker and spatula, but the protagonist just responds with the generic 'That won't do any good' response. Not okay."
"The puzzles are sometimes quite obscure and the game does not really help you either: Often you get generic answers and no hints on how to progress. I felt reminded on Discworld's 'That does not work'."
"I got very frustrated and didn't know how to move on"
"Some difficult puzzles I needed to use the walkthrough for"
"The dialogs are full of typos and incorrect English (the German translation is also done poorly). Many of the puzzles feel random and there are too few hints that nudge you in the right direction"
"the dialogue for some of the characters does not use phrasing that you would expect from someone in that position. I have already encountered typos as well, so that makes me a little worried for the rest of the game"
"The lack of sufficient signposting at times will make many gamers glad that The Legend of Skye comes with a complete walkthrough"
"as well as inventory puzzles that are sure to remind players of the old adage to try everything on everything, since solutions aren't always so easy to come by."
"Other puzzles can be quite daunting at times, too, since it's often unclear what you're supposed to do. You'll wander around collecting a bunch of inventory items quite easily, but without a clear idea of where to use them exactly. Indeed, The Legend of Skye's signposting leaves something to be desired."
"it also can border on frustration, with many puzzles that are a bit too layered for their own good. If only Skye would comment on what you were trying to do – not giving solutions away, of course, but perhaps just pointing you in the right direction."
"Cons: Lack of signposting may make the walkthrough almost a necessity at times"
"The Legend of Skye ignores 30 years of quality-of-life improvements."
"Imagine my frustration when one puzzle directed me to send a paper boat downstream and recover it before it reached a certain point. Easy enough! Except, no, the game wants me to put a coin in the boat and fish it out with a magnet attached to a fishing rod, with zero dialogue to nudge me in that direction or reason why Skye couldn't just grab the boat or use her reach-extending poker to redirect it, as she'd already done several times already."
"Without resorting to a walkthrough, you'll wander from place to place mashing items together without ever really knowing why. I'm well aware that most players approach these games knowing that puzzles are everywhere, using anything they find on everything they see accordingly, but it feels like the puzzles were designed with that in mind, with solutions like those above making no sense or not being alluded to by the characters."
