 ### Key Python API (`mcrfpy` module)
 The C++ engine exposes these primary functions to Python:
-- Scene Management: `createScene()`, `setScene()`, `sceneUI()`
+- Scene Management: `Scene("name")` object
 - Entity Creation: `Entity()` with position and sprite properties
 - Grid Management: `Grid()` for tilemap rendering
 - Input Handling: `keypressScene()` for keyboard events
 - Audio: `createSoundBuffer()`, `playSound()`, `setVolume()`
-- Timers: `setTimer()`, `delTimer()` for event scheduling
+- Timers: `Timer("name")` object for event scheduling
