Bounce orbox from block to block to get to the exit or complete other missions.
Excellent puzzle game when you want some mind challenge! Move in 4 directions. What's the catch? Orbox will keep move untill it hits the wall. Sounds simple? It starts simple but every level will be more difficult and intresting!
