LOVE the idea of health and ammo intertwined together! Very pleasantly surprised when I played your game - I had a lot of 0 planes chase after me and I didn't want to waste any of my ammo, and I'm curious if you wanted to add an attack where you can use it without using your health ammo, like a melee attack? Something that could help get rid of those 0 health ships without spending ammo? Maybe you could have a boss where you have to spend your health to activate specific mechanics, like it activates an opening? Either way, You did a phenomenal job with the amount of time you were given! Good luck with the rest of the jam!
