Root cause: startFollow used lerpY=0.05 + roundPixels=true. At rocket velocity (~1400 px/s) the camera lagged ~466px behind the player, then snapped in chunks every frame, giving the impression of low FPS / shake. Fix: - Replace startFollow with manual upward-only camera tracking that matches the player exactly (doodle-jump standard behavior) - Disable camera roundPixels so antialiasing actually smooths motion - Round bg tilePositionY to integer to avoid grid texture shimmer - Slightly thin out boost effects (flame 3->2/frame, speed line 40->65ms) to keep frame budget headroom on weaker devices
