The project is designed to be imported into your mobile HTML5 games. It resizes the game to fit the window (keeping aspect ratio), and centres the game. If the player rotates their device, they will be shown a message asking them to rotate their device back. By default, this is shown when the device is in landscape mode and the available view is less than 500 pixels tall. Both of these can be changed. This project includes just one sprite and one object, plus a demo room. To use in your game, simply import the sprite and object and place the persistent object in the first room of your game. You can of course replace the sprite with your own message asking the player to rotate their device. Click here to see a game using this engine.
