omg i am flying threw bubbles with 65 to rank up and i hit one of those yellow bubbles and lose like 300 bubbles D: And i can hear myself going down to level 1 as i write this comment...
Make a Bowl of Adamantite, then cut a small hole in the bottom and replace i with steel, Then fill it with thermite and light it. (zombies below the hole would be better)
Not to turn down a great idea but don't you think movable people would be a bit exaggerated? Now, it would be nice to make things like: lases, laser sensors, switches, etc... [+] if you agree
