Today was a busier day at work, so I didn't get to do a whole lot. But I did excise the old chain-of-green-arrows path preview code in lieu of a preview mode that shows hexes you can walk to given your current number of movement points, as seen above. It's a quick hack, though, that doesn't cache the set of reachable hexes; instead, it's testing them each frame which means the pathfinder is being called quite a few times each frame, something I'll probably fix tomorrow, given time. It "feels" better to me than the path preview before, gives me a more tactical feel.
And that's... well, that's about all I was able to get done today.
