"Toggle switch click, satisfying mechanical"
```

### Game Audio
```
"Coin collect sound, bright and rewarding, 8-bit inspired"
"Level up fanfare, triumphant, short celebration"
"Footsteps on gravel, walking pace, outdoor"
"Magic spell cast, ethereal whoosh, fantasy"
"Explosion, medium distance, cinematic impact"
```

### Ambient/Background

"Rain on roof, cozy interior, thunderstorm distant"
"Office ambiance, keyboard typing, air conditioning hum"
```

### Cinematic
```
"Dramatic bass drop, tension build, trailer impact"
"Whoosh transition, fast camera move, action scene"
"Door creak, horror atmosphere, slow and ominous"

```
