Thank you so much for your support, I'm very happy about that!

Regarding the tree reaching the end of its stage (level 5), I haven't thought about that properly yet. The only idea I had was that to keep the game "alive," the tree, upon reaching the last level, might live for another 30 days or a little less, and then it would die, and you would have to buy a new seed.

This might seem a bit bad, but by my calculations, any tree you buy that reaches the end of its "life" gives you back what you invested in it plus several hives, so you can maintain a certain "profit" from it, and buying new trees also stimulates the economy.

But it's just a thought; I still have to analyze very carefully if it would actually work that way.
