Players shouldn't worry about whether their complaints and criticisms of the game are being too harsh. If something is not good, players should say so. It's the right thing to do. Players should always just honestly express how they feel, whether good or bad, without worrying about hurting the company's feelings. This isn't a kindergarten, and the developers know that. The feedback is here is probably summarized anyway before being given to the team (if it reaches them at all). Our feedback helps them learn what makes us happy and have more ideas about how to improve the game in the future. They shouldn't necessarily always listen to our suggestions, but they should at least be aware of how we feel, and why we might feel dissatisfied with the game.
