Congratulations. I think there is much more going on in the background that I see. I am not a huge fan of idle game, but this is personal taste. The game flow is quite interrupted due to the transactions. Is there maybe a way to do less transactions? But maybe this is exactly the purpose and the innovative part of this game (sorry, I am not so deep in the blockchain technology). One thing I would have a closer look at are the prices of the units (in-game). For quite a long time it is better to build the smaller one instead of the more expensive ones.
I like it that you openly state from where the assets are.
