* Fix rendering of children * Game loop handles other restore * Properly propagate onMount and onRemove to children * Use BaseGame on gestures to minimize confusion * Fix linting * All children don't need preparation * Add composability example * gameRef might not be defined * Add mustCallSuper * isMounted on game * Remove unused gameRef argument * Made isMounted only modifiable by the component * Move dartdoc to public isMounted * Fix formatting
