ANIMATION & ACCESSIBILITY

Last Bell Studio respects your device's reduced-motion setting. If spins, rolls, transitions, or celebrations look shorter than expected, you can enable the full visual experience here:

Windows 11: Settings → Accessibility → Visual effects → Animation effects → On

macOS: System Settings → Accessibility → Display → Reduce motion → Off

The apps remain functional with reduced motion enabled.
