Hey Chris,
I’m also checking this forum again and responding! ;).
Currently when the hero walks, he’s restricted to tiles. Pixel precision means that the hero is not restricted to tiles anymore, and can walk anywhere he wants, and also diagonally. Most Action RPG games have this feature. See https://twitter.com/koonsolo/status/625233688188571648 to get an idea.
So I’m currently finishing that feature, and after that I’m going to do a pretty technical thing that you won’t notice. But it will allow me to find and fix bugs way faster than now. So that also means I will be able to free up more time to work on features :D.
