Luminosity Relax Into A Zen-Like State With Puzzle Retreat
The Voxel Agents, developer of the Train Conductor series, is back with a brand new game featuring nothing less than a block sliding puzzle. Puzzle Retreat wants you to chill, man.
Shut off the outside world. Relax, unwind and focus with a new type of puzzle that is both simple to learn and compellingly deep. Taking inspiration from Sudoku and Sokoban, Puzzle Retreat is a fresh challenge that will have you losing track of time and forgetting about the outside world.
