First of all, thank you for PocketMine, it is a nice piece of software! I had some fun installing it at home and teaching my child a little about servers as we played creative together on our server each on his own tablet. Might open it to his friends to connect in order to safely introduce them to MUG. I have a question more out of curiosity. I've noticed comments on the latest 0.8.1 compatible release that carts weren't implemented for the same reason as mobs. My question is how far are you from implementing mobs, and, if it is far what is the key challenges you are facing to implement them. I have a technical background, programmed complex corporate systems in Java and other languages, feel free to talk tech, patterns, etc. Add me here. Thanks & keep up the good work!
