Hey, not bad
This was pretty fun to play because it was extremely simple and reveled in its simplicity. The best thing was how the balls seemed to just merge with each other. That made it easier to avoid them. It was far from perfect as it did come off as being a little too simple and could have used some more detail. Putting in a blank background is almost never a good idea. The thing I found also annoying was how that music seem to just continuously loop when it was just the same beat.
You could improve by putting more detail and selecting longer loops of music to use. Of course, you can just turn it off as I now realized so it's not so bad. It is still fun as the game itself is quite fast paced for looking so simple. Most of the time I just go in the same direction but that does eventually fail me. You could also use some work with lines as the blue design does not look impressive.
