One i mentioned was how over powered the darts are. The tardigrad have no chance if you hit them with a dart. Now if it took 2 darts to kill one maybe giving it a 10 to 15 second duration would make it more realistic. Also noticed that if you didn't pluck the dart from the monster after the fight that it would not show up on the ground some times. That said I wasn't using a blue mushroom at the time to verify.
