Why does the physics in the editor diffrentiate from the ones in my build?

Hello there! The friction in my build seems to be quite different from the friction in the in-game editor. Because in my build i can't move left and right without setting the speed to like 200 (normally it's 2) , whilst 200 in the editor would make me fly out of view. The reason i think it has something to do with the friction is, with a speed of 2, i can move in the air if i jump (yeah jumping works completely fine in the build) though the movement in air is still slowed. **My code:** https://hatebin.com/awynhmhgso **Video of movement in the editor:** https://i.gyazo.com/62558dc1da16ed3bb4b36d7fc3848155.mp4 **Video of movement in build:** https://i.gyazo.com/b3397df45f9be7465d5d15659c3f3a85.mp4
