There are small updates and then there are small updates. 150-300 renders IS a small update; 40-45 render update is a joke (and I don't mean that as an insult to the dev, it's strictly about the update size, not the quality of his work, this way of updating is certainly going to lead to frustration for many possible fans).
That is like, what, two minutes of gameplay? It's not worth downloading, it's not worth starting the game.
If I know it, fine, I can wait, but it still is kind of weird to see a game pop up in "latest updates" constantly.
