excellent !

Wow, awesome game, but it needs numbers to mark the speed and radius so I can say "20 speed and 50 radius." And that will mean something, and others can copy it and see what I've found.
Still awesome game with cool patterns, love it.

I will give it a Crappy rating if I want to.

What the heck is the point?
I give you 1 because that is how long it entertained me, 1 minute.

Well executed!

I can't nitpick anything about this except the synaesthete in me wants a more polished GUI and the ability to add glow/PS type effects to the lines whilst drawing.
The geek in my however, loves it. Hee. :3

Nice...

I liked it...
Good job mate.

Amusing

It's pretty fun to change the speed and radius, nice job!
