Blue is a 2D puzzle game where you play “Blue”, a little blue cube who wants to change his world. You accompany him on his journey, guiding him through a series of progressively more difficult levels. Along the way, you're likely to meet other characters... who knows what links they may have with our little blue cube. Bleu's progress in this world will perhaps enable it to evolve into something better. The game takes the form of a series of puzzles, the aim of which is to “slide Bleu” to an objective. However, some of the levels depart completely from the original gameplay. The difficulty increases progressively, but finishing the game is a real challenge. Hundreds of levels, boss levels and a wide variety of puzzles await you! Can you rise to the challenge?
