A more uniform spread can enhance gameplay balance by avoiding the clustering of entities near the center.","author":{"url":"https://github.com/Rapen765","@type":"Person","name":"Rapen765"},"datePublished":"2024-10-19T20:16:26.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/2425/arcade/issues/2425"}
