Like the game! Would like it if the difficulty were a bit more consistent--it seems to go from the player taking no damage at all to getting killed off fairly randomly.
Nice work!
It's time based using OnTriggerStay , so if you have 3 of them touching you at the same time you will lose 1hp per second per NPC.
Ohhhhhhh, okay, got it! Maybe clearing that up in a quick tutorial would help?
