I have some ideas about the game.

1. It would be a good idea to make the old planets a little more rare. So that old players have advantages over new ones. You can simply learn the experience of splinterland.
2. The game lacks notifications. Sometimes it’s very easy to miss an enemy attack. I can’t keep track of all the planets at once.
3. Removing the JSON? Why not? This would speed up the game. I don’t think it’s so necessary to record every action on the blockchain. See how fast DrugWars works after deleting JSON-transactions.
