When you pull out the first point of a curve, it's oriented backwards. Here's what I see when I click on the left point of the circle, drag the curve handle upwards, release, and move the cursor to the second point: http://imgur.com/zw20Ig4

I get the same behavior on the next exercise (the heart), as well.

Also I feel that you are giving exactly enough points to do a nicely editable shape, and then asking them to do it in less by having the score mechanic. I'm at the face now, and every preceding image has been done with exactly the amount of points allocated when I follow my usual rules of point placement. I feel like you're teaching people to make hard-to-edit images by asking them to use less points.

(Said rules: 1. Pull curve handles out to about 1/3 of the length of the line they control. 2. Never turn more than 90º between two control points. 3. Avoid S-curves between two points.)

OSX 10.9.4, Safari. And fourteen years using Illustrator as my main artistic medium.

Edit. I stopped at the swooshy S when you asked me to try and make it with about 3/4 as many points as I would consider to be the minimum for a nice, controllable path. I feel you are teaching people bad form.

(To make a programming analogy: think of the difference between ultra-compact, hyper-idiomatic Perl code with single-letter variables and nicely-commented code with informative variable names - the Perl may be smaller, but it takes a lot more effort to go back and read when you need to change something.)

Great game! For me, the issue is this: the direction that you drag when you're doing your first anchor point is the opposite of the direction that it should be. You're dragging away from the direction you want it to curve, rather than towards it. But for every anchor point other than the first one, you're dragging towards it.

Author here. That's the way Adobe Illustrator thinks Bézier curves should work, unfortunately. I have no idea why,I chose to follow their lead because the purpose is learning how to use a tool. Still on the fence on this one, I even had to go out of my way to implement it.

If your copy of Illustrator does that with its curves then something is direly wrong with it. I've used it since 2000 and it's never done that.

Awesome idea, but unfortunately unplayable. The first point is oriented backwards, as many pointed out here. Pressing Alt is constantly popping/hiding Firefox's main menu, shifting the display up and down.
