make the ball's reaction to the subtle changes of the platform even more. increase it's snsitivity to the platforms movement

after the ball falls after a certain point, it should stop reacting to he platform, but this point is currently too large. reduce it
User prompt
reduce the point after which the ball can no longer be controlled by the platform even more
User prompt
the game enter game over before the ball actually touches the ground. wait for it to fall to the bottom before going to game over

the ball's contact point with the platform is too large. reduce the contact point of the platform
User prompt
after the balls falls off, the rotation currently stops, but that looks unnatural, as based on physics, it's rotation should continue due to inertia, so keep the ball's rotation even after it falls

now you made the ball be more sensitive, but the ball's rotation is too much, so while you should keep this sensitivy, the ball's visual rotation should be lower, so it doesn't rotate as much as it looks unnatural
User prompt
the ball stays too balanced on the finger, so if I only slightly move the platform it's still very balanced. the whole idea is that the player needs to move the platform to keep the ball balanced, but since the ball stays too balanced it never falls. make the ball be more sensitive to the subtle changes in the platform's movement, to that it moves left and right even at slight changes in the platforms movment

Please fix the bug: 'Uncaught TypeError: Cannot read properties of undefined (reading 'y')' in or related to this line: 'ball.y = platform.y - platform.height / 2 - ball.radius; // Start from the top of the platform' Line Number: 85
User prompt
there's a bug where the ball is invisible until the platform moves, which is a bug, it should always be visible on the board from the start of the game
User prompt
the ball's rotation should concide with it's horizontal movement, or viceversa, so it the ball rotates clockwise that should coincide with a movement to the right. right now the ball rotates but it's not moving, which feels weird
User prompt
add a limit for the hand, so that it can't move all the way to the edge of the screen. if the hand tarts from the center of the screen, it should only be able to move 200 pixels to the left and 200 to the right, until it can no longer go any further

the whole point of the platform is that the platform holds the ball above it. however, right now if the ball has fallen under the platform, but I quickly move the platform right above the ball's Y center, it instantly teleports it back from under the platform above it, which defeats the purpose. this is a bug, fix it, as once the ball has fallen under a certain point, it shouldn't be teleported back up
User prompt
go to game over if the ball touches the bttom side of the screen

User prompt
after falling from the platform, the ball can currently be relifted by using the platform, however since the ball has already fallen under a certain point fro mthe platform, instead of being relifted it should just be pushed away, as to make it feel mroe natural.

after the ball is almost ready to fall off the platform due to the inbalance, it's pushed with a very hard force horizontally, instead of naturally falling around the platform, as if being attracted by gravity. fix this, so the falling feels more natural
User prompt
Simulate Friction and Inertia for Rotation: To decouple the ball's rotation from platform displacement, focus on the ball's horizontal movement as the trigger for rotation. When the ball moves horizontally due to an imbalance, this movement should influence the rotation. Implement a simple form of inertia where the ball continues to move in a direction until friction (a decreasing force) gradually stops it. The rate of this horizontal movement can then be used to determine the rate of rotation.
