Thanks so much for playing! I'm sorry there is a lot going on and it's not super intuitive how to grow larger plants. I may record a short video time lapse of one of my play through for anyone who wants how it works.
Thanks for the heads up on the UI, I'll add it to the known issues when I get home, not sure I'm going to go back in and fix it for this project because I don't know what's causing it yet but I'll absolutely try for the next one or if I expand this one!
