The sample sound on the Shimmer plugin is too loud (-2.3 dBFS with 0% reverb).
Depending on the reverb settings (and other subsequent effects), the audio will eventually clip heavily and jumpscare the user! The level should be set to something more appropriate such as -12 dBFS.
Moreover as a second issue, it will also play the sample sound on click release, leading to two consecutive beeps. My common sense tells me this isn’t the intended behavior.
