The enemy jump takes approximately 0.75 seconds (47 frames). For those who have played a fighting game, you can practice anti-aircraft using familiar commands (623 etc.). I also try to get anti-aircraft skills on the bottom pool. In order to be able to cope with turning, the command (6321) and the command (62321) are designed to produce anti-aircraft. Anyway, it is an application for practicing anti-aircraft with one hand.
