Just tried the unexplored mode - 2 things that would definitely need to be changed:
- Be more gracious with revealing black tiles, it happens that a scout has plenty of a tile in vision but it doesnt reveal it till it goes way in the tile
- When you zoom out the mex symbols dont get rendered properly (maybe a side effect of hiding them on minimap?), makes it very hard to find mex that you explored
I think if those 2 things are addressed, it would already be quite playable
