As many people have already said - Editing the description would help a lot! I went back to the rating page to figure out mouse did something. But I tried resizing and lots of different things.
After I figured out how to change the colors it was go time. I felt like a white ninja square moving quickly between blue and red. I liked being able to resize for my perfect visual sweet spot. This game needs a lot of focus, so it was nice to make it my personal size.
Good work!
