Android and Apple device users who crave an MMO experimental sandbox platformer are in luck. Seth A. Robinson and Mike Hommel (Robinson Technologies and Hamumu Software, respectively) have released yesterday for free Growtopia, which explores the crafting part of Minecraft, while trading the mining for growing.

Specifically, everything in the game can be grown from seeds of trees, including lava and jet pack trees. New trees and items also come from mixing and trading the seeds. Players can apparently find most of the items quickly, so the in-app purchases don't feel forced. Growtopia also employs an innovative lock system that protects players' creations and allows players to share access to them with friends.
