I could only play the web version embedded in your ldjam page, there seems to be a problem with your itch upload :
Unable to parse Build/LD53Web.framework.js.br! This can happen if build compression was enabled but web server hosting the content was misconfigured to not serve the file with HTTP Response Header "Content-Encoding: br" present. Check browser Console and Devtools Network tab to debug.

Besides that, I love the graphics and the system seems very solid and interesting. I had trouble guessing whose turn it was to move but that may be just because of the <div> on ldjam that is too small for your game.

Pretty fun turn-based strategy game you've got here! The chunky pixel art is nice, and the XCOM-lite gameplay is relatively intuitive and enjoyable. I really like the idea of having to recover souls in the field and bring them back to base before you can spend them. The health system works well and I like how the individual hearts show instead of just a bar. The tutorial at the start is really nice, too, and helped me get right into the action. Great work! :)
