My Orders new indie Android game

Exciting game “My Orders”, in which you need time to deliver the order to the desired floor. The game difficulty lies in the behavior of the elevator, which will be described before level. The game is made in three forms: morning, afternoon and night. You have to play in each of these cycles.
Managing the game is very simple, you just have to hold your finger up or down to move up and down, respectively.

► 35 Fascinating levels morning, afternoon and night.
► challenging levels, multiple endings
► Nice music
► Smart pause and simple interface

In my new version of my game:

► Added language selection, translation of the game
► Fixed size right panel pause
► Spend inversion sound buttons

Current version: 1.1
