Sure! Here's a simple game that meets your requirements. It allows the player to slide across the screen by swiping, and the character automatically jumps when the screen is tapped. Please note that this is a basic implementation, and you may need to add more features and gameplay elements to make it an engaging game for the App Store.
To use this code, you can copy and paste it into a text editor, save it as a .html file, and open it on a web browser. You can then interact with the game by swiping horizontally across the screen to slide the player and tapping the screen to make the player jump.
Remember to further enhance the game by adding obstacles, scoring system, and other features to make it more engaging before publishing it on the App Store. Good luck with your game development!
