So this maybe was discussed often after the climbing update got realeased, so here is the idea.
Climbing itself is cool and with the tower it shows how it works. Then future updates comes and maybe new locations come, how about having climbing points that only work if you have a partner to climb. So how would it work, it is like the friend request mechanic. Both people would need to hold thier hands to climb together. You coud throw a person up or pull someone up. Wich would make teamwork in climbing.
The problem that can occur is that the stamina drains faster wich means that this kind of climbing is optinonal. Like if we get new tower treasures and there are two ways, a longer taking solo climbing or a duo shorter climbing.
For my own thoughts it would make climbing more used because we only have people doing the tower challenge and after that they only climb some buildings which for some people dosen’t make any fun.
