Polished minimal puzzle game

I like the simplicity of this game. The puzzles look easy, but then they're not and you get sucked in. I love the clean lines and graphic style, not to mention the mesmerizing music!
@jacqvon This looks really good! I love the black and white minimalist design of it too!
Really cool, I specially like the fluidity of the graphics. Does anyone know what game engine was used for this?
