Thank you for playing the game and for the feedback! Unfortunately we didn't have much time to adjust the sounds as it was one of the last things we implemented, we are sorry to hear that it negatively impacted your experience, that is definitely something we will adjust in the future :( The hint button was hiding a tool, each tool is different each round, we wanted the player to only know what the tool was after clicking on the box to open it! There was a tool under each cat because you can use the tool on either or both cats! Thanks again! :)
