This update aims to improve overall performance and make the early game more enjoyable. For those who have already played a lot, if this patch doesn't include significant new content.

I had a good discussion about the "prestige" mechanic in the game, particularly how it encouraged players to wait rather than take action. After experimenting with a few ideas, I settled on a solution that addresses this issue. In the future, I plan to introduce upgrades that allow players to retain more resources or even gain additional resources during the prestige process.
