I love this game, but, do you think we can add a hard mode? I'll list off some stuff that could be in this said hard mode:
-Plants grow more slower than usual
-Certain events that happen that prevent certain plants or animals to reproduce or grow
-predators kill way more prey than usual.
i think adding a hard mode into the game would make the game more enjoyable over all, as it forces more experienced players to invent new strategies to keep their Vivaria up and going!
(Yes i am aware that this is supposed to be a relaxing game, but it can also be a challenging game for those who wish for more difficult gameplay, like me :D)
