Thank you for the comment. We designed the game to include a heart rate sound effect. The heartbeat rate would correspond to the heart rate shown on the UI, rising or slowing down accordingly, but we didn’t have enough time to implement it. In the game setting, when the heart rate is too high, the character would breathe too heavily, making it impossible to use the whistle, and a gasping sound would play. Unfortunately, we couldn’t add these features.Thank you for playing!
