We assure that you have never played this kind of game. Consider that you are playing a 3D adventurous game calling Suspense and you can adjust the map according to challenges such as gaps. For example, when you encounter with the gap including beaked bars, press the one of 1, 2, and 3 keys to change the map. Be aware of the possibility of that there can be differences between maps. For instance, you are at higher level in one of them, but when you change it, you can die due to the beaked bars. Good Luck!
