As Shadowvaal said, we do appreciate the effort you are putting into reviewing games from this site, and we do invite you to do more reviews, because it's currently rather quiet.
As a developer and reviewer myself, I'd rather have someone being blunt rather than sugarcoated. Sometimes however there is a fine line between being blunt and flaming. You also should ensure that you at least read the topic post. In the case of Nexus if you had read the topic post, you'd have noticed that English isn't his Native Language.
Getting a balance when reviewing a game can be hard. Try not to focus just on what you feel are terrible games. There are some brilliant games around, Try reviewing them too...It will mean you don't end up having your reviews ignored, because some readers will think you are just wanting to review bad games, and will not actually like to get reviews by you, whereas a balanced but honest review means people will come to you for reviews!
A good reviewer on this site is actually Amerk. His review of Spirit Timer
was fair but honest. I messed up with quite a few things, however he handled it with stating the BIG game breaking issues without saying that it was a complete disappointment of a game, and that he hated me for making a game breaking bug. Obviously this is a different style, but using better language helped me to work on my game and develop it better and further, because of his honesty
I personally love your style of reviewing, it has a great structure. It's in depth and honest/blunt and I'm looking forward to seeing more.
