Space Riddle Brain Puzzle

Space Riddle is a mobile puzzle game made by me. It consist of 60 levels, starting easy and getting more difficult. Game grid has 9 tiles - 1 with spaceship, 7 with obstacles and 1 empty. You can move tile next to empty one unless it will collide with any obstacle. The goal of each level is to move ship to the position marked as exit, so it can fly away without any collision.
