Overview
Play the packaged Super Mario All-Stars plus Super Mario World Improvement SNES game offline in a focused Chrome popup.
Super Mario All-Stars - World Improvement puts a locally packaged SNES platform adventure in a focused Chrome popup. The original game is the default mode: open the extension from the toolbar, choose Start Game, and play without requiring an account or a connection after installation. The compact shell keeps the game centered while the control dock remains available throughout the normal play flow. The included Game Guide explains the verified keyboard mapping in plain language. Use the arrow keys to move and navigate menus, Z for the SNES B button and jumping, A for the SNES Y button and running or grabbing, X for the SNES A button and spin jumping, Enter for Start or pause, and V for Select. If input does not respond, click the game area once to give it keyboard focus. Restart restarts only the currently selected mode. World Sprint is a separate local HTML5 mini-game for a short optional challenge. Move with the arrow keys, jump with Z, collect the coins, and reach the flag. It is clearly secondary to the original SNES game and never replaces it. Favorite is a session-only visual toggle, and Share uses the browser sharing option or copies the game address when available. The extension does not require sign-in details, profiles, analytics, telemetry, or persistent user-data storage.
