Restless twins: the boy and the girl are on the road again and this time you will accompany them and help in the game Flap Flat Twins. You can play both together and alone. If you decide to play, controlling both characters, switch between the characters and move in turn. To pass the level, you need to collect all the diamonds. Kids are able to deftly jump, jumping on platforms of any height. It is enough to have supports in the form of vertical walls in order to push off from them and have fun jumping up. This ability will be needed by siblings in all levels of Flap Flat Twins.
