Not telling people to give my game 5 stars and I will give them 5 stars, but just asking people to rate my game and they will post the links to their games in the comments. So we both get more fair rating which boosts our games.

When you comment on other peoples games your link to your game is attached. Which is a really nice thing that itch has, you can check out other games, but we want to avoid pressuring anyone to do anything, but asking for feedback, well we have the place for you in our discord. Come in and lets get you known :D

I already did it a rate for a rate. I doesn’t think that really works, the rates are lower, I think. And globally , I am not a big fan of that. JollyJoe is right: asking for feedbacks (on discord) without giving something in return is better, but you can play the games after if you think they worth it. And when you comment others, they can see a mini-picture of your game, itch.io is already asking for you (with the picture).
