Thanks so much for taking the time for playing my game! I'm glad you had a lot of fun with it, as for the health... I'm pretty sure you had ZACH MODE on because it makes it so you never take damage.
Well, at least I learned from my time in Zach Mode! Stopped at wave 18 because the difficulty had hit a plateau, but still a lot of fun! Definitely a much more challenging start without Zach Mode on 😅
