Our forum member TheSlider wanted to know if I could make the terrain graphics less blurry. That was the last straw! That broke the camel's back! That... Well, it wasn't so simple as changing a number, because the terrain graphics were dynamically baked into one texture to speed up rendering, along with all the plants. I had to make all the plants into actual sprites that now have a height and can appear over rocks.
In the end it took just a couple of days to do it, and I don't think it's much slower, in fact there are less skipping frames when moving. It looks a bit better, but I'm noticing some scaling artifacts, so I still have to work those out.
