Port game from Cocos2d ObjC to Unity Tiny

Port game from Cocos2d ObjC to Unity Tiny. The game is a simple 2D game that works on iOS with touch gestures. It uses level data in form of strings, loads them, displays them in a simple isometric way and renders the character on the current position. Each move of the character is countes as a step. The goal is to finish a level under a certain step count. The activity of the character is almost not animated, only the direction of movement triggers a new sprite. It plays a sound on movement and game over. Some levels have interactive opponents, with no AI, but a simple heuristic pattern. In this project, you would start a Unity Tiny project and port the functionality of the 2d game from Cocos2d Objective C to Unity C#. There are about 1000 lines of code in the Cocos2d version and 20 graphics.
