whenever i try to join my friend or host the game crashes help[

I know the point is getting from bottom to top on 1 go, but I like to play with my friends who have jobs so we do not have that much time to sink on retrying. It would be great as a game option, like just add like the check where it transfers the boulder on each milestone of each challenge....

Всё равно кто ты парень или девушка, главное без душнил и школоты плз. Я парень 18+ с микро и дисом. Хочу просто поиграть после работы на чиле. Я новичок. Плюсуйте сюда или добавляйтесь в друзья. Всё....

Or is the co-op mode only available online?

Game keeps crashing when i try to host game or join friend
