Got stuck on level 8 but I had fun. Simple concept but cool puzzles and look. The music was nice. Could use a UI element to tell the player what level they are on. Do you plan on adding more?
A Level Tracker would not be hard to add. Don't plan to add more levels as this was a learning project to get me familiar with working in a grid and developing a game from start to finish. Next project will be larger in scope after finishing up the feedback given on this game.
