When your in the rhythm of it this game it works very well. I think the usual trying to rush trough a puzzle game because of the fear of it get boring on a quick look is what is causing them to get stuck.
A tip when answering a question in this game is to type answer(yes/no) + Keyword, not just answering no as the game will not know what the answer is in correlation to. Also re-watching the answers is the key to finding the keywords, guessing mostly gets you stuck and frustrated. The game usually wants the phrasing the character you talked to used.
