Note: I'm not saying you're wrong for feeling the way you do, and I get it because I've felt the same way about other games, this is just how I've managed myself in the past.
I feel you're applying a bit too much pressure to this project. Like you're wanting it to be something it can't be. You made this evident in one of your earliest comments on the project iirc. I don't think this game, with a small team (or even less), is ever going to reach the expectations you place upon it.
I think it's justified to want it to be better, but you have to also consider whether or not it's realistic that a small team could make it as better as you think it could be. Ask what it would take for features to be added, the time, sometimes cost, and what you'd need to do. Not to mention life effects and how that often intertwines with developing, modeling, drawing and so forth.
There's a lot that has to be done, a lot of stuff that takes time. Realistically, you're not going to get these features, that sometimes takes month to get right, out monthly or even consistently. Sometimes you're lucky if you get it out at all. Really, to me, the issue isn't it not getting out.
I feel like a lot of people would just want to hear what's going on. I find that it's often a lack of communication in these projects that causes disconnects between devs and players. If information was made available and project updates, even if it was just blogposts, would be more than satisfactory to people. It'd create a bridge between player and dev, and would let us know why things are the way they are, and why things have to stop for one reason or another.
