If your game needs menus, feedback sounds or a bit of atmosphere, these are free:
- Essential UI SFX: 150 soft, neutral UI sounds: click, hover, confirm, cancel, open, close, notify... 5 versions of each event so nothing repeats
https://willosuna.itch.io/essential-ui-sfx - Cozy UI Kit Lite: warm pixel art UI: panel, dialogue box, buttons, checkbox, toggle, hearts and bars
https://willosuna.itch.io/cozy-ui-kit-lite - Pixel Weather VFX Lite: 8 seamless rain, snow and ambient overlays
https://willosuna.itch.io/pixel-weather-vfx-lite - Pixel Weather SFX Lite: 12 rain, wind and nature loops and one-shots
https://willosuna.itch.io/pixel-weather-sfx-lite - Magic Spells VFX Lite + SFX Lite: pixel spell effects with matching spell sounds
https://willosuna.itch.io/magic-spells-vfx-lite
Sounds come as WAV + OGG, graphics as transparent PNG. I made all of these myself, drawn and synthesized from code: no third-party art or samples. Free for commercial use; a credit to Willosuna is appreciated.
Good luck with the jam!
