That's not surprising that you didn't see much from it. One update then abandoned. So far I've only seen this on itch.io and its only popped up 3 times. Release, Color update, Discontinued. Although the only encounter was enjoyable. It was 10 mins of game play then done. I was just waiting for more content. From my side it seamed Barely Working was more complete on its release then this was. And it received way more updates. Each post brought me back to check it out.
Weather it be a story mode or just a chain of bad guys. Just anything to do. Introduce 2 more girls and 5 new guys, they don't even have to be different combat style just recolor them and maybe a change the hair. Let the player pick one of 3 girls then send the groups of 1-3 bads at them for 3 mins. Then send the boss you already have like Streets of Rage or River City Girls. Or put all 9 characters in a grid and do 1v1 through the hole line up like the old Tekken
