If you don't write for yourself, you're never going to go anywhere with it, you might as well close it down.
You remind me of those bloggers who are always asking for feedback or comments on the topics they are writing about. (I didn't see you do this.) They are notoriously bad bloggers cuz here's the PROTIP, nobody wants to read a non-expert. I want to learn something from an expert on a subject, not some newb who's asking me for my own opinion. You may not think of yourself as an expert but you can be. You are an expert on your own project and the code therein.
Most bloggers don't start to get a readership for years. 2 years, 3 years, 5 years. You're not writing for your fans, you have to write for yourself, and then you'll eventually figure out a rewarding and interesting style of writing. You won't know though, unless you write. I once did a stint where I did satirical writing. I loved it and my writing was good but I noticed people actually believed my writing and so I was a bit uncomfortable with misleading people.

Right now your posts are too specific to your own games, which I find uninteresting cuz I can't play them as far as I can tell. I wouldn't even post about a game I was working on except in a promotional, one day you can buy this, sense. Instead perhaps you can write about specific coding ideas and concepts. For example, what is your way of programming multiple balls at once (if you allow it). Do you program them as completely separate entities or do you loop through an array? It looks like you put thought into inputs, how exactly is that setup.
Instead it looks like you paste long lines of general code and talk about it. Your code is also completely unformatted and not styled on the blog. Anyway, I would post about specific things instead.
I would say posts about AppGameKit probably is going to be of interest to only a small handful of people. If I were to estimate probably less than 1000 people regularly use AppGameKit (though perhaps even less than 100). It also offers no modern programming paradigms, and so is of no interest to anybody using OOP or functional languages (the majority of modern languages).
So you have a blog discussing a relatively little used engine, procedural programming, about a monkey ball clone and you're complaining about a lack of commenters. I think some of your stuff is interesting. Your song was neat, how did you write it? What are some of the musical theories you used.
If you want my comment on that, I thought the song was interesting but the drums were not thought out. I would never go with a boom ta boom ta drum loop. It's super annoying. I'm sorry to tell you this because now all the songs that use the boom ta beat (and it's a lot) will perhaps annoy you as well.
Put in a real drum loop and I think you'd have a winner there. That said, I would use a boom ta beat on something like a racing game or some other speedy type action sequence. The beat lends itself well to fast and forward moving scenes.
