How to play game
A formula will appear when it's your turn to attack.
Pay close attention, because it will quickly
disappear and reappear in an incomplete form.
Memorize the given equations and choose the correct answers
from the panel as fast as you can!
During your opponent's turn to attack,
tap the screen at the right time to avoid the power vectors.
You can jump up to 2 times,
but miss the timing and you'll suffer major damage!
