This was actually experimented with during beta, and the feature was removed because it made inequalities between Glitches so prominent. Unless Tiny Speck decides to entirely rethink this philosophy, it seems unlikely that this will ever be reintroduced to the game.
Ive tried to help a few with small things like meat etc. but once I click on the info bar and find their level, theyre gone =P The differences in the level is what makes this game fun, I think. That way you get to make friends with people your level and asking higher leveled people about things relevant to the location youre in, instead of using the forum. That makes the game more personal in my opinion =)
Only works on trees and animals on my browser at least + you have to click the X and then click on the character again ;) I use Google Chrome, maybe it works differently in other browsers?
