Oh, that's what those triangles are. Ok, I think I'm starting to get it. You may want to make those something other than triangles. Triangles look like arrows which suggests direction, creating an unwanted association. I'd just put circles or squares there instead, and maybe write "AP" on the left side of them. Being an important element, they also should be in more contrast towards background. In action cost popups they're white on yellowish background, which is barely visible.
This new version is a bit easier on the eyes. One of the main causes of clutter are orange range markers of your units. They're just too thick, big and eat up all space. Those should be made subtler; perhaps thinner lines or just semi-transparent shapes without lines.
I'm not sure if the action points should be shared though. If they are then each live unit should at least add to the total at the start of turn. Imo it'd be better if each unit had their own.
I managed to bring enemy's hp bar to zero but it just refilled again. I'm at the same time happy and sad about it :D
