Hi,
I played the game and I had a lot of fun :) The satisfaction you get from completing a puzzle is just amazing! The puzzles are well-built and pretty balanced too. I do have one problem though: the game asks me to 'answer', but nothing appears in the circle, so is this a bug or is this intentional? Except for that I can only say you did a good job on this game, the music feels good and the art is simple but good for this type of game.
Keep up the good work!
