Thanks so much for your feedback! I understand that the initial interaction needs some clarification and future features shouldn't be mentioned in the descriptions. The interface on the side is still very basic, you have a good idea for grouping things! I was also thinking of having an "overview" tab that mentions your total gen / sink for the whole plant. There's a lot that can be done there for sure!
I also understand that upgrading needs to be clarified more... the idea is that the upgrades only apply to your next plant (when you hit the "launch seedling" button) - which is not very visible! I definitely need to clarify when that button appears and gets to 100%.
This is great feedback, good to know where the major pain points are! I'll make these improvements and more in my next update!
