Code Runner is a top-down 2D programming game for Android mobile that will be developed in Unity. The player must navigate through each level with the provided movement functions they have in order to get to the goal as quickly as possible. Take the first level for instance, it is simple and straight forward so that learning how to play is self-explanatory: The player will be provided with a single movement function “Player.forward()”. If the player touches this function, they move one node in front. Four nodes ahead of the player will be a treasure chest, once they reach it, the player will open it and receive “Code Bag”. The code bag allows the player to collect more functions in the later levels, i.e. Player.right(), Player.left(), Player.back(), Player.shoot(). As the player gains more functions, the levels become more complex. Certain nodes will provide advantages to help the player reach their goal as quickly as possible, other nodes will hinder them (e.g. mud to slow the player down). Eventually, the player will have access to a function named “Repeat()”. The player will have the opportunity to insert other actions (like movement methods) in this function, and as a reward, have their movement speed increased whilst the repeat function is active.

Allowing the player to re-do levels once they’ve completed them means that they can use newly picked up functions that they’ve earned from later levels to reassess their route and complete the level in a quicker time.
