Also, if you will be continuing this mod anytime soon, I have a couple suggestions.
-Diamond Tools should become really weak in durability. After all, diamond tools IRL would not be very strong.
-A way to see how much thirst & energy you have
-A flint shovel would be good.
Also, how do you smelt iron? I can't anymore in 2.0.0.
recently rediscovered this account and the memories have been flowing back, let me tell you. it's INSANE.
