In Flop Flop we have to keep the overview. We run with "W,A,S,D" and look around with the "mouse". We can run wherever we wan, there is no gravity which stops us. Our goal is to reach the green cube. To finish the level we have to get a position where we can use "space" to free fall into it. This key will do a 180° flip and is the main game mechanic to use and finish each level.
