# ideas go here
# lifecycle of a plant
# seed -> seedling -> sprout -> young plant -> mature plant -> flower ->
# pollination -> fruit -> seeds

# neighboring plants can cross pollinate for different plants
# health based on checkups and watering

# development plan
# build plant lifecycle just stepping through
#   - What else should it do during life? growth alone is not all that
#   interesting.
#   - how long should each stage last ? thinking realistic lmao

# interaction
#   - look at plant, how do you feel? (also gets rid of pests)
#
# events
# - heatwave
# - rain
# - bugs
#
# build multiplayer
# neighborhood system
# - create plant id (sort of like userid)
# - list sorted by plantid that wraps so everybody has 2 neighbors :)
# - can water neighbors plant once (have to choose which)
# - pollination - seed is combination of your plant and neighbor plant
#   - create rarer species by diff gens
# - if neighbor plant dies, node will be removed from list
#
# garden system
# - can plant your plant in the garden to start a new plant

# build ascii trees
