Streets of Rage 3 is actually kinda hard, much harder than the 2nd game for sure.
But everyone loves SoR 2 ,and I think that's exactly because it's an easier game. You can set the difficulty level to "Mania" and have a real challenge, or just play on defaults and breeze along the game, having fun.
And I am interested in playtesting this project
Even more if you keep on having an ECS version
