💡 Features 💡

• Animations: animate Transform, Material, UnityEngine.UI (uGUI), UI Toolkit, AudioSource, Light, etc.
• Custom animations: animate any field or property of type float, Vector, Color, Quaternion, or Rect.
• Delays: schedule delays, set timers, and use PrimeTween as a non-allocating alternative to 'WaitForSeconds()' and 'await Task.Delay()'.
• Easing functions: choose a standard easing function, provide a custom AnimationCurve for animations, or use Parametric Easing to fine-tune the standard easings.
• Shakes: shake the camera, Transform, or any arbitrary property.
• Callbacks: execute custom code when animations complete.
• Sequences: combine animations, delays, and callbacks into complex sequences.
• Inspector integration: all animation properties are tweakable from the Inspector. Tweak start and end values, duration, cycles, etc. Choose a standard easing function or provide a custom animation curve. All without re-compiling the code.
• Coroutines: wait for animations and sequences in coroutines.
• Async/await: await animations and sequences in async methods.
• Cycles: repeat, play animations back and forth like a yoyo, or cycle them indefinitely.
