Bad Street Brawler

Battle arcade. Creepy, old, but not without its advantages. There is one thing that annoys me: in a game designed solely for fighting, the combat system should be praiseworthy, or at least work without glitches. This is not the case here. As for the graphics, I'm interested in two things: 1. Why is it not possible to hit while jumping (why do you need that button)? 2. Why do all the hits pass you when you sit down? This trick easily lasts the whole game. Trying to play without it feels like a giveaway.
