UE4 Menu and Launch Problems

Hi there! I have some problems…
First : How should I launch level with my menu?
Second : I made a game with Unreal Engine Tutorial on YouTube (EndlessRunner), but if I launch it as standalone game, I move just as ghost (no clip I think), but if I launch it in ViewPort game normally launches with a Character running forward
Third : Problem with turns - since I go into turn, my Character can turn only in 90° but can’t dodge anymore
Image : This is how my menu is looking (First is Start Game, second is settings, third is credits and fourth is exit game)

I can at least help for the loading of a level…For loading a level you can just assign a “on clicked” event on the designer tab to the play button.

In the graph tab just drag off of the “on clicked” button and select “Open Level” then just type the level name in…
