Gamescom demo and combat worries

I heard a video game journalist say that he saw Control Resonant being played at Gamescom, and he said that it didn't convince him at all and Dylan always makes the same moves, you can only do one combo. Is that true? Or is the demo just smaller? I really like the game and won't let others influence me. Did any of you try the game at Gamescom? If so, could you share your thoughts?
