Pretty Good
Hmm, I wonder if you got the idea from Ball Revamped... Oh well, doesn't matter. Anyways...
This game was fun, kind of. It started out fun, but then slowly became boring. Then the vibrating walls started, and it was fun again, but that got boring too. Then the intense vibrating walls started, and that was fun and very challenging, and also the most challenging part of the game.
Personally I think you should have flipped the flashing walls and the red vibrating ones, because the last 20 levels were really easy.
By the way, a tip to anyone stuck on the red vibrating walls: Just stare at one square, and fixate on it, it'll dispell the illusion of vibration. Or just cover the edges which makes it feel like the box is moving.
Another thing you could do is add an option to turn off the music. I did like the music in a lot of levels, and found it pretty fitting, but still, after awhile I wanted to just turn it off.
Overall, good game, but definately could be improved by adding more interesting levels, and a music option.
Good job! :D
