I really liked this game, it is exactly the genre of games that I would play, I like the genre of puzzles and thinking to solve problems or challenges. I think it does need music; something relaxing instrumental or slow classical music. I also recommend using more contrasting colors for the walls and the goals, because sometimes I didn't know which was the goal and which square was a wall. It's a good game, I would play it a lot if I had the time. Good job!
