Day 2!
Not much was achieved today due to tiredness, but the plants can now be converted into cuttings and the cuttings will 'remember' the heights of the plants they were taken from. You can also now select up to two cuttings from the bar, but you can't actually do anything with them yet. That'll be the next step!
The floating numbers are the 'heights' of the plants and the cuttings, and basically just for my own reference so I could check everything was working as intended. They'll get removed before the game is released. (0 is short and 1 is medium! The first target plant will just be a tall version of the starting plant.)
