For anyone who wants their menus to sound and look as unsettling as the rest of the game:

• Horror UI SFX Lite: 30 dark interface sounds: click, confirm, cancel, error, open, close, save, alert, reward and more.

• Essential UI SFX: 150 neutral UI sounds, 5 versions of each event.

• Horror UI Kit Lite: 19 pixel art pieces: rusted panel, dialogue box, buttons, hearts, skull and a health bar.

Every sound ships as OGG, so it drops straight into audio/se (WAV included too).

I made all of these myself, drawn and synthesized from code: no third-party art or samples. Free for commercial use.

Good luck to everyone!
