I'm not sure if those are syringes or sword...probably swords but when he talks after they keep attacking you, but you can't see the heart and your health is going down then you die. I'm not sure if it is a glitch or a bug.
no. its clearly a part of the game. he will start spawning attacks after a certian point even when your not in a "fight". the number of these spawned attacks increases over time. you just have to react quickly and dodge them by going to another button
