The game stopped working at some point, possible there was a messge or something off screen.
I can understand what you were going for, I'm not sure the music really fit well, or it would have been nice for some variation, and the art was simple but it could have worked if the game was perhaps zoomed in on the player some more and with some nice animations.
It would be nice to see what the area of effect could be when you hover over the cards because many times I picked a card and then it was wasted because no enemies were close to me. It also would have been nice if the enemy itself lit up or rasied up when aiming instead of only the tilemap square, especially in isometric, because sometimes I missed my target which was also frustrating. Feedback to show you hit or to show your player got hit would also help a lot
I can see what this game wants to be and I think it could be something enjoyable but definitely need some work.
