Parents need to know that Apple Knight is an action game for iOS and Android devices. The game features a lot of violence, and while there isn't any blood or gore shown, the main character faces numerous physical threats, ranging from bats to balls of fire. Players can sometimes avoid other characters by jumping over them, but otherwise may fight them, primarily using a sword, until they die. Players can purchase items such as coins, which can be used to obtain new abilities, for $0.99 to $49.99. Ads are a pretty frequent occurrence and appear between levels if you die, but players can often click out of them soon after the ads start. The guidance they get when they begin to play doesn't explain all aspects of the game -- they may still have questions about how to open treasure chests, for instance, or see an instruction to light a checkpoint fire, but not know why -- and there's no FAQ or other resource to check for answers. But the gameplay is fairly intuitive, particularly if they've played similar action-quest games before.
