Open the game in Safari and play with touch: tap to walk, tap things to use them, and hold for more options. Use Share, then Add to Home Screen, for a full-screen icon. A keyboard and trackpad work too.
Open it in Chrome. On a Chromebook you can play with a mouse and keyboard: click to walk, right-click for options, use the arrow keys to turn the camera, and press Tab to switch to WASD movement.
School and work devices often block installs, and tablets fill up fast. A browser game needs no space and no permissions, and your character is saved on the server, so you can pick up where you left off on any device once you’ve added a password.
