Proposal : Increase the UMY cost for breeding

Summary: Our current consumption system in the game is not good enough, and the consumption and mint of UMY can be more balanced. I suggest increasing the cost of UMY per breeding so that the price of UMY will be stable and our income will be more stable. Taking a kara breeding as an example, the specific costs are as follows:：

Breed times UMY cost/breed NOW UMY cost/breed Expected

         1                                 150                                            300

         2                                  300                                           600

         3                                  450                                           900

         4                                  750                                           1500

         5                                 1950                                          3840

         6                                 3150                                          6150

I hope my proposal can be approved that we can really increase the price of NFTs and UMY that we own now. I love this game and want to play it for a longer time. Compared with other similar games the only concern of me is the consumption of the game will directly influence the price of NFT/UMY that I have in my wallet.
