This is my entry for the competition, I may tweak a few things and add level select, but it's pretty much done.
Also this is my first game, and I must say that Construct 2 really is brilliant for creating this kind of thing, your imagination is the limit!
Well here it is: http://www.scirra.com/arcade/rotary/538/splat
Any feedback is greatly appreciated =)
Also, runs best in Chrome, but works pretty well in all, even IE!
Should also run on less powerful machines as I tested it on a netbook throughout and used Delta Time =)
