- Worked on Memory Lanes, a 3D logic game for iOS where the user needs to reinput a pattern shown by traffic lights in a cartoon city. The player is a car moving around the city.

There are a number of items that can be used to help the player progress (replay, skip, life refill, and more), but they need to be earned or bought.
