This project is mobile game based on my experiences as a drafting engineer. The name TAP comes from the term Third Angle Projection. This game teaches the player about third angle projection through logic-based puzzles. The design of the game was heavily influenced by modern web and app design from sources like Invision. Each game mode requires a different page layout. These layouts are unified by a grid system that is used on every page. All pages and levels work as set due to this strict system. The final result is a refined engineering inspired game with fun and educational puzzles.
