You can reset the deck to reset everything, as the white bar used to... Y'know, attack with moves pretty fast. ATT and DEF save so don't worry. Basically the formula I used is Damage = ATT×Accuracy÷20-3×def And accuracy is depended on .1 scales If you hit it above 0.4 units or more, the accuracy is 100 – the units away from the black box × 10, 0.3 units or less is 110, 0.2 units or less is 120, and 0.1 units or less is 150 accuracy, or a critical hit. I'm probably the first to make one of these.

Basically, just tap the screen in the middle when the white box enters the black box. If you miss, just restart the deck.

You can change the ATT/DEF with the buttons below. They're 'when a touch begins on this' type of button.
