What is Train of Thought?

Train of Thought is a cozy, logic-driven puzzle game where you take direct control of a toy train in a vibrant diorama world. Solve clever logistics puzzles by coupling wagons, navigating tricky tracks, and delivering cargo with precision. With its intuitive controls, soothing visuals, and fail-forward design, Train of Thought is perfect for players who enjoy relaxing yet intellectually challenging experiences. Let your mind stay on track!


Development

Train of Thought is a vertical slice developed as part of the final project for the Master’s Degree in Video Game Design and Development at the Universitat Oberta de Catalunya (UOC). It serves as a polished prototype that encapsulates the game’s core mechanics, aesthetic vision, and overall gameplay experience. Built entirely in Unity 6 LTS, the project reflects a thoughtful approach to cozy, logic-based puzzle design, set within a vibrant toy-like diorama world.


Goal

The game has been conceived from the outset as a viable commercial product, with a clear market focus and defined target audiences. While it was created within an academic context, Train of Thought represents a proof of concept with the potential to grow beyond the classroom — both in scope and in scale. Developed independently as a solo dev project (excluding the use of licensed assets), it lays the groundwork for future expansion into a full game, and serves as a strategic foundation for pitching, publishing, or self-releasing in the cozy puzzle game market.
