Your game is looking great! Thanks for sharing your progression
I understand the development is still in progress, but I have one small remark : either my contrasts are high enough for me to clearly see the ball but the grays are black, either I lower the contrast to get correct gray but I can barely see the ball, as it's moving. Could you make the balls maybe one or two pixel wider ? But then it would be taller than a brick, so i'm not sure it's a good idea. Or maybe add a trail to the ball so it will show up black instead of gray.
