Really nice entry, I enjoyed this a lot!
I liked how you managed to create four different mini-games, keeping consistency between them at design and controls level: I imagine it's not easy, but you provided a complete and cohesive game! Congratulations!
My fav was the one with clocks; I solved it before understanding the hours clues :P
I believe each clock controlled different parameters of the geometric transformation of the drawing; is this correct? If so, I would love to play more levels based on that concept, it was really fun :)
