デベロッパの回答 、 We are very sorry for the inconvenience that you have experienced. To be honest, we are not expecting many players to purchase the hints, which would turn this into a pay-to-progress game. We do not want that to happen. We hope that players can sit back and enjoy the process of finding clues by themselves. This is part of the reason why we sell the hints, instead of giving them away. Everything that you essentially need to solve the puzzles are already in the game, either as part of the story, or patterns that you can see in the scenes. The hints are there to help those who really have trouble figuring out certain puzzles. In other words, the hints are not necessary for completing the game, but can be helpful on occasions. If you need any help with the puzzles, and do not want to purchase the hints, you can send us a screenshot to our twitter @CottonStudio, and we will give you some instructions. We apologize again for your dissatisfaction, and thank you for playing our game. If you need any help, feel free to contact us. The wall in this scene is clickable, and you can get some hints from it.
