Boy, they are really attached to each other. Separate them for 5 seconds and they die. Really cool game mechanic :) (P.S. you can fix the camera issue by setting the collision channel of the spring arm component to ignore the "pawn" channel)
Thanks for playing and for the tip, I was trying to fix that bug but couldn't make it time. Also I did a rookie mistake, which was decreasing the health on Tick (each frame), that's why you died fast since i'm guessing you have better gpu.
That's actually how retro games used to do it when the hardware was always the same :P Multiplying by delta time should do the trick, then you can keep in on Tick.
