I found this game very challenging and interesting. I like the relation with the number of movements and the eyes but it took me 2 or 3 tries to understand the mechanics... nothing problematic (I'm from the 80's.. no tutorials back then) but these new generation could find the game hard to understand. My only complain goes to the user experience when unlocking new levels. The UI has replay and maps... it should have next level also!
Other than that, it's a fresh concept... I've never play a game like this.
Congratulations!
