Whenever I play multiplayer, or with my friend, my character goes almost crazy. Usually when I hold the left mouse button my character follows the cursor, but now he went south east, well only one direction. And When a tapped a spot on the ground for him to go to he twitched/lagged and then went (its a little hard for me to explain), and 1 more thing. When I would want leave a level for example or just go through a door, it didnt let me? Like, it didnt show me the cursor thing for me to accses it. Really enjoying the game tho! (all of this happened co-op mathes)
