Baby Zombies are OP, not possible to live if there are 2 or more

Baby Zombies, combined with new sword mechanics, are too OP. Severe balancing needed. It may not be possible to live if you encounter 2 or more on hard mode. Because they are so fast and have SOOO much health (way more than normal zombies it appears) there's no way to successfully defend. You cannot wait for full recharge of sword and you can't hit faster due to little or no damage. Their speed, increased hitpoints, and the nerfed sword contribute to a major fail.

Not playable, not enjoyable, needs to be adjusted.
