Cute little entry! I like your idea to control a group that also represents the health of the player, it's a nice interpretation of the theme! It reminds me of similar mobile runners, but sith a top-down adventure twist =p.
Gameplay-wise, it is a bit simple, but efficient =). I would have liked a bit more guidance to be sure I didn't miss anything, because I went to the end and destroyed every monster here, but probably missed a couple of them earlier ^^'.
Overall, it's a nice little game, congratulations =)!
