Hi i played in your game. I would to give you my feedback. It isn't hate or negative critice I will write what i like and what I less like. So, i very like graphic an mechanic, especially rotating the board. Graphic is minimalist but estetic, clear and look nice. Ofcourse idea was good too. I like mathematic puzzle so much! But.... Sorry for this, but I don't uderstand your game. I know what i must to do, but I have no problem with choosing the right door every time. I quickly found a way to win this game without solving the puzzle on each level. Try to do something that makes playing a little difficult and will not make it so obvious. Maybe add new maps or something that will bother you.
Your game is cool but it can be even more fun. Great job! Don't stop developing your passion and skills! :-)
PS: Sorry for my english, i still learn.
