Pressing R in the game-over state calls __init__ on the same instance, but the previous after chain created in loop() is never canceled and loop() always re-schedules itself even when game_over is true. After each restart, another timer chain keeps running, so updates execute multiple times per tick and the game speed/collision behavior becomes increasingly incorrect.

Because restart re-enters __init__ on the existing window, this line creates a fresh Canvas each time and pack() adds it to the UI without removing the previous one. Repeating win/loss + restart cycles will stack canvases and grow resource usage/window layout unexpectedly instead of resetting the same board.
