Thank you so much for playing the game and taking the time to share your feedback. It truly means a lot to me and is the highest compliment I could receive.
Sometimes I'm surprised that people either don't know about some of the features that are right in front of them or simply don't use them. I'm referring to the text effect.
As for your questions: the game contains a pool of 25 questions, with 10 of them selected at random for each playthrough. So you may not have gotten the question about the arrow and the apple, although you most likely saw the target and the arrows.
In the Russian version, the question was: "Did at least one arrow hit the bullseye?" ("bullseye" here is a play on the Russian word яблочко, which literally means "little apple" but also means the center of a target.) That wording doesn't really work in English, so I had to rewrite the question. Instead, it asks about an exact match between an arrow and an apple, and that's why there are apples scattered around the target.
The question about the books is actually quite straightforward. It can only be answered by reading the books. Each book in the room has a letter on it, and when you put those letters together, they spell either TRUE or LIE, which gives you the answer.
Once again, thank you very much. I really appreciate you taking the time to play my game and leave such thoughtful feedback.
