I'll say it again, SWF's are useless. Really nice job with the animation, though. Feel free to animate your robot, but remember if you do you HAVE to supply the FLA. I'll be sending PM's to those who have only submitted FLA's.
Nobody else who has already submitted needs to change anything. We're already taking your robots apart and animating them if necessary.
But for future submissions, please send them as a FLA if you have Flash. Indicate the depth of each part by putting them on separate layers. Here is an example: http://www.newgrounds.com/dump/item/e25e c794ae3802692731b11001127f92
Also if there's anything that would need to be moving in your robot, please animate it.
If you don't have Flash, please submit your robot parts as separate PNG files to make them easy to import into Flash. Remember that they need transparent backgrounds. Name them whatever you like as long as they include your robot's unique name. Bear-1, Bear-2, etc. is fine, or Bear-Head, Bear-Legs, etc. is also fine.
On the subject of creativity, remember that the legs part doesn't actually have to be legs. It can be wheels, treads, a hovering unit, anything.
