Time is running out, so anyone else want to vote?

I voted for This End Up. It appears to be a close race between Sparks Factory and This End Up. I voted for the latter, because of the amount of creativity involved, but the difficulty may be beyond what is desired. It's still a feat to overcome in my opinion, and that is what I think makes the level fun. I found Sparks Factory to be a bit easy compared to the rest (still not "easy" as in beating the boss on the first try); I might even find it very easy if I played it more. It has good EC in my opinion.
