Thanks for the response.
It's good to know how game devs feel about feedback. I'm thinking about doing a review type for games and demos called "Likes and Suggestions" (as posted earlier in the thread discussion). I'm hoping to give productive, specific feedback without being negative like "pros and cons" can be.
However, as I learned from a previous response by Krunchy Fried Games, I'll probably ask the game dev if I can make videos of their games and what kind of videos I can make. And if they want a review of their game or full lets play etc.
