A and D to move from side to side, purple platforms are guaranteed to move, spike platforms kill you, slime platforms make you jump higher, gray platforms are normal, wooden platforms...(Jump on them!!). All of these platforms has a chance of moving. Collect coins scattered around the tower, and buy skins with them(To get to skins menu, when you die, don't click restart, but the button next to it, and then you can scroll through the skins by clicking the arrows). The bottom left corner shows how many coins you have, and you can see your score while in play by looking in the center of your screen, or when you die, you can see your final score. Skins info: Every skin has a certain jump height(how high you jump), and the more expensive the skin, the more jump height.
