For some reason, you have to click the flag multiple times to restart the game. Use arrow keys to move, click for menu selection, and space to talk and continue text. All you can do so far is explore the island. Be ready for updates including more NPCs, weapons, collision detection, and monster battles. [Btw: Muns is the currency (money)] IMPORTANT: When selecting a weapon, Use arrow keys to see the options and click to select.
Be ready for slow updates fixing the art style to something more concrete.
