I have a list of suggestions for the developers to add into the game. Firstly, Maybe switch the gems into another currency in the shop whenever the player is low on coins. Example: The old price for the No Advertisement was 2000 coins, if unable to afford with coins, they may use their earned gems. Secondly, Please add spawn eggs and weapons/more resources like food into the creative menu in a private map. It's only private maps which only the users can use and doesn't really affect other game modes. Make the game-mode switching in Private Map Settings free. The gems are a great feature, But I suggest making it free or, like I said, use coins as another currency. Next is the enchants. Switch the enchants to experience points which is also another request. Maybe add more kinds of tools like diamond. Add emerald tools or amethyst / more minerals to make items with.
And more skins, and less mobs in mansion
If there was experience points, then poc would be just be similar to minecraft. There should be difference between the two.
And also remove lags and make the game lighter, cause for me the game is like 20-30 mb (megabits), a lot of ram required
