I agree with Cjindel. You can also give a decent, respectul review without being rude and just coming off as an angry gamer who couldn't find their specific requirements meant in this specific game. Yes, there's room for improvement but is a demo? is not the final product, and while I am always rooting for feedback whether is positive AND negative on any type of games to help the creators improve, you need to learn to communicate your opinion without being snarky.
