Ryan - Dolls are featureless and will remain featureless. If you want faces, make them yourself. (Read the FaQ) Wild - There was an update 3 days ago. Be patient. Tomas - Select (shift) your creation, then right click and press "create custom item". Then type in the name and press "save".
Wet - You already can. Click the button that looks like Earth. Declan - You realize a new update came out two days ago, right? Don't expect a major update every day.
Kirito - What are you even talking about? The joint limit? Also, how is the snake in the knight vs. snake level broken? Was it because it can't move? That's because the creator accidentally made joints to the background. Just cut them. It has nothing to do with the joint limit. Old levels also didn't have any joints removed, you just can't make more joints on them.
Daniel - Do you mean spawned or from the harpoon gun? If from the harpoon gun, then it's not a glitch. If spawned, then what are the steps to replicate?
Irizarry - Use the drag tool to make them move, trigger (F) their hands/head and put an item near them to make them "equip" them. Other things would probably be AI.
