The great box and circle shoot out!
I'm sorry, what?? This is your 100th submission and... this is it? Graphics are apalling. Sorry to say but.. there's just a bunch of boxes and circles, some moving, on the field that blow up. You need to seriously concentrate on graphic design and improve your work that way. I still can't believe this is your 100th submission. The graphics look they're from someones 10th submission.
The gameplay was.. average. It's easy and repetitive.
My advice is, don't just make flash. Learn from each one and use what you've learned. Quantity does not win over quality.
