Very very nice mod but there is still something to do
Something you should add:
-Splash potions of harming heal you and vice versa healing does damage
-Slow destroying doors
-A bit slower running
-That NPC should be really nice
-Spawn with some random armor
-Try implement option you can use your skin or normal zombie skin (Or zombie villager)
-Idle sounds of zombie
Something that should be fixed/removed:
-At first quickly remove that big hand
-Spiders are attacking me (I noticed this at you are the creeper mod too)
-Spawning:When day you will spawn in a cave, but when its night spawn on a surface
-Some item that you can take a other zombie on skeleton (But only like a friend i don't like big armies recruiting)and it could be respawning with you.
By this way thanks for this mod i have been waiting for it for ages.Thank you if you read this post and forwardly thanks for reply .
