It took me a long time realizing that the squares are the units HP, i thought for a long time it's part of the tileset on the ground for some unknown mechanics, i would try lower their position and check how it looks. great submission tho!
Thank you! I didn't have time to get the hearts up (I had already drawn it) so it just got left as the placeholder square. Sorry that the game was so confusing! I appreciate you playing it though!
