Alright this thing really needs a gui. Typing /consume purifiedwater constantly for just 10 thirst to go up sucks. Also /consume berry which only improoves hunger by 1. Lots of clicking too.
1.) Balance the different foods. Ex. Banana seeds are harder to randomly find or pick from the tree, but each banana ups more hunger. Make there be a progression of available foods. Mushrooms may be the lowest. Then berries and so on... Mushrooms only up 1 hunger, berries 2, bananas 3.
2.) Make the consume command allow for an amount value. This way it doesn't matter that berries only up hunger by one because you can eat 100 of them if you have them.
3.) GUI, GUI, GUI... This game mode screams gui. Players can trade all that typing for button clicking and it looks prettier. Plus the time wasted typing causes it to be harder then needed to be.
4.) I like the trees and stones and what not, but maybe modeling some more blocko looking stuff would be cool? This defiantly works for now though.
5.) Health starts a bit high. Levels need a little more balance such as 50 health for a lvl 1. Then 75 and so on through the levels.
6.) Relying on other peoples add ons is good for now, but some things should eventually change. for example the color set.
I'm not saying anythings horrible just as before i am constructively criticizing. This is just what i thought of after testing this game mode out.
