The visuals and music are sweet! Controls are not so great but I see the gameplay style you're going for. I also thought the switching qwerty azerty was a little silly because it mostly came down to: Does this level make me use A or Q to go left? Keep working on this, though! I'd say just ditch the keyboard changing aspect and focus on what makes 2d beat em ups or 2d platformers fun: the responsiveness of the controls. Definitely gave me Blasphemous vibes
