Hi, I rarely read the reviews posted on this thread, and will continue to do so.
I see some people complaining that I've been developing the game for four years and there's still not enough content.
There are several reasons for this. Firstly, I can't make the game full-time because I can't make a living from the income from the game. I should buy a more powerful computer which is about $4000. (And that's just the cheapest price.) Also, it's the first game I'm developing, so I had to learn a lot at the beginning. And I'm still learning... I am not an iron man and sometimes I am sick or simply exhausted. It's very easy for someone who hasn't developed a game to make negative criticisms. "This game sucks because of that, the other game sucks because of something else", but by the time that "sucks" is done it takes a lot of work even if it really sucks. And that's what people often forget.
Have a nice day!
