no save its because its trial demo. I like the game and graphics but its way too damn complicated. It tries to be realistic by not using blocks everywhere but it ends up to be too confusing to build a simple shit.
I have to say though that the performance is better than mythruna on my pc maybe because its using DirectX i dont know but again too damn confusing
Or maybe it's because they've actually optimized it.

DirectX and OpenGL are using the same hardware. It's the hardware that makes the graphics fast or slow.
In the screen shots, the horizon also looks ridiculously close.
There are many places I can pretty easily optimize Mythruna's engine but writing the game is the hard part... and enough people can play that I get testers so there is no point in spending 6 months optimizing the engine and still have no game.
