A WHITE text on a BLACK background

is telling you that in order to play the game you have to tap left or right / press the keys (on pc) so that you take PUFTEA to the last floor: 1000 score automatically stops the game and you become the winner

TIP:

platforms gradually shrink as the score gets higher. if you are stuck on a lonely platform, take the risk and teleport to the opposite side by jumping towards the side closest to you.
