As fleetp said you have to press "Space". What resolution you are playing on? After that go to "Settings" and change it, but I will work on the splash screen now to support your screen, which is not 16:9 or at least not in the game for some reason.
Well without entering the game proper, I can see selection screen floating icons which are overlapping with other options, which I'm assuming is probably a continuation of the resolution ration issue. This is present in every screen I've been on including the settings (I really don't wanna screenshot every page so I've only included 2). The resolution is in the proper setting for my monitor by default, and using an improper (1920x1080) but supported resolution does seem to put everything in it's place.
