Nice work!
This was extremely well done. Everything runs really smoothly, whether it's gameplay or just switching between the different screens. Your music choices were good as well; nothing overpowering or annoying to listen to after like the 4th loop. The backgrounds you used were great as well. They weren't completely plain, which is a plus, but the designs were subtle enough not to draw your focus away from the actual mazes and distract you. As for the actual gameplay, this is definitely a fun game, and I think you achieved a nice balance with the difficulty. The levels aren't ridiculously easy, but they aren't ridiculously difficult either. Overall I like it a lot. 5/5, 10/10. =]
