Hello, thanks for your feedback.
1. I agree with this. Seeing the reaction of players, the 'hint room' will be changed into a 'rule room' in some future version. This room will contain clearer rules instead of the cryptic hints.
2. Giving rewards would not fit the character of QT4 or the theme of The Magician. As for choosing the room, players can select one of the three main rooms by controlling the view count (it can be decreased slowly by not taking any action for some time, and it can be increased accurately by then struggling against bindings). The rule for room selection may be changed in the future to only consider the last digit of the view count to further help with this. I believe that this system will also become clearer to use when the rules in the hint room are made more clear.
3. I am not sure if I understand this comment? It's not possible to save during escape sequences. If you wish to try the highest difficulties of escape sequences, it's recommended to try this by challenging them in the memory room.
As for escaping The Magician, you can also leave the escape sequence by taking no action for some time (QT4 will kick Lily out). As with the other hidden rules, this rule may also be made more clear in a revised hint room.
