Sleepy Jack is a game developed and published by SilverTree Media for Android and iOS. It was released on December 15, 2011 and delisted on December 8, 2017 (due to SliverTree Media mysteriously shutting down along with the other SilverTree games). While there are APKs for the Android version that can be found and downloaded from various websites, the iOS version (IPA) however is nowhere to be found.
