Pretty much a tech demo right now but the frame rate is excellent (thanks for the frame limit option). Also in the future please include a invert Y mouse option for the dozen of us that still use that. Its gonna be some sort of mining and demon killing roguelike I think which seems cool.
And well I don't know how much this matters but there's a frame or so when destroying voxels where only black is rendered, like this:
frame1
frame2
