I just wanted to give a friendly reminder to give GOOD feedback on every game you play. I've seen way to many comments that say "good game" or the like, but never give any useful feedback. Don't be afraid to tell someone what you didn't like about their game and why you didn't like it. The "why" you didn't like it is important too. It doesn't help to be told there's a problem but not be told what the problem is. In my experience (not much) comments that tell you what you did wrong are 10x more useful than comments that tell you what you did right. So in recap every time you play a game, give the dev something, anything that they can use to improve their game or make themselves a better dev.
Here's my format that I use when writing comments. The way you write your comments is completely up to you, this is just me giving an example:
1. Open with what I liked most. list 2-3 things
2. list 1-2 things I didn't like
3. explain why I didn't like those things
4. (optional) give a potential fix for those things if you think you know a good way
5. tell them good job. cause any dev who managed to submit a game deserves it.
P.S. WHATEVER WHATEVER WHATEVER WHATEVER you do DON'T be that one guy who spam comments a rate request on every game without playing or rating the game.
