Yes, use the clusters link on the page. I'll link it here, but it's just the link on the main page:

The game is $30 USD, which may be displayed as $870 NT for you. You can search the cost up if you don't understand; it's just being displayed in different currency. If you have any questions, feel free to ask here, or use the discord - you can also find all relevant details on either the LonaRPG page, or Clusters where you purchase the game.
