For the 7 Day Roguelike game jam I've created NoMad, a turn-based RPG set in the Mongolian desert.
For this game I've used Unity's tilemap system. When you enter an area the level gets randomly generated. The algorithm behind this level generation is based on Conway's Game of Life. By tweaking some of the algorithm's parameters I managed to create cave-like levels.
This game definitely needs some polish and tweaking, but I'm pretty happy with what I've achieved in 7 evenings.
