This game fits the theme well. Pretty solid gameplay loop. My biggest issue was understanding all the game mechanics. I like what you did with the health bar, but it's not super intuitive. I think something like a line of circles would have helped make it easier to track the health instead of the indicator traveling through open space. Maybe even make the circles disappear as the indicator passes them.
Also, I didn't understand the ability to move the player's pentagon at first. I realized later that your player circle needs to be in the center and not moving.
Good job with your game overall, it was fun to play!
