You know, I'm honestly puzzled at where you think the MC is this way. I actually hate games like that as well. Did you stop playing halfway through it? You do know that he grows and changes as the story continues, yes? You're describing the very thing I also hate about some AVNs. My stories do not instantly show people at their best because to me, that is unrealistic. So, you have to read it all to get the whole picture.
Early in the story, he IS a dumbass. I wanted to show him growing and changing. So, without you getting snippy and rude, try speaking normally and give me an example from the story. Because what you're describing is exactly what I abhor about other games. I know I made him a little naive through the beginning. And there is a part where he (understandably) doesn't want Kat to get pissed off. This is a fairly human situation. You describe him as a baby, crying in a corner sucking his thumb. I know damn well I didn't write him THAT bad. I admit I fucked up a lot of things through the beginning of Serenity, it was my first VN after all. Much of it will be getting rewritten.
If you don't want to respond, and just want to move on, that's fine too. But this is how criticism works my friend. You tell me what you like and don't like, and I add things to my list of things to fix later down the road. Try having a conversation like this with other devs and getting a response. For most, you won't even hear back. I make it a point to engage with my followers and work to improve and learn what people like.
Finally, no offense, but small advice: When you go on a dev's site and post your critical review, try being nice maybe? And then you get a nice response and maybe even help make the game better rather than pissing off the dev. Keep in mind that making these things is NOT easy. Most devs are not professional writers - I am definitely not, but I think I improved over the course of making my first VN, given the work and time I put into it and all the shit I dealt with to even complete chapter 1.
