Will there be an update and do you (PawPunch) have any ideas, if not, here are a few:
1) You can add a new location.It will be like a branch from the main location in the form of a path in the forest that will lead to a lake, sea, river or ocean (you choose). Where it will be possible to find water-type Pokemon and add a new way to improve relationships , for example, to fish them or feed them the same fruits from a tree and lure them with the same, if there is a question of where they will be located , if you catch them , they can be in the water and they will only be half visible . You can also add a room with a swimming pool for "mating".
2) Since I was playing the game, I saw a stone structure in the main location and most likely you added it in order to add evolution for Pokemon. I do not know much about evolution stones (namely, where to get them) so you can add a location with a mountain in which you can mine them (they will appear in cracks and you will need to click on them in order to pick them up) . And in order for Pokemon to evolve, you can add the "Call for evolution" button.
I hope that you will notice this message and maybe add these ideas to the game in the future. Reply to this message, add, don't add, or think about adding or not.
Thanks for your attention
For PawPunch.
