I really like this! Great use of the theme. It started to get strategic for me because towards the later wave, so many health spawn and if you accidentally pick one up , obviously you get weaker, so you can choose to have higher health or take the hits and gain higher damage. Love the use of grey hearts by the way. Gives me the chance to survive while i can deal a great amount of damage. I totally abuse them :') Im on wave 15 rn
