| Please draw for me perfect circle first for me to follow ?

| Its ideal circle is centred on the dot

| I got 20% by drawing an ellipse

| A nice square gets me 77%. Good enough for me.

| Thumbs superior for some reason

| Drawing a triangle resulted in a score of 77.9?

| martyvis wrote:
| Fun, but needs more rewards than just a high score. Maybe

| where you need to target a given radius. Anyway, nice job.

| zamadatix wrote:
| As a tip: what it's really checking is for a circle centered on
| the dot in the middle with the radius equal to your initial
| click's distance from the center. You could make a mid sized
| perfect circle which is slightly off the center of the dot and
| lose to a square that fills the play area.

| I was wondering why some circles seemed great but got low

| My anticlockwise circles score more than my clockwise ones.
| Is there some theory behind that ?

| ynfnehf wrote:
| By cheating with a Python script to move the mouse, I managed to

| A mac or windows app controlling the mouse I presume?

| 100% perfect circle is a pure math thing and can't be achieved
| with drawing in any way.

| Cool. Actually harder than I thought

| Another great neal.fun page. One feature I'd like to see is, make

| something. Right now you can just spam hundreds and take your top
| score, but it doesn't really reward consistency.
| majkinetor wrote:
| Yeah, we all totally need consistency reward. The game will

| Your limbs etc are all a collection of ball and socket/downright

| want to use this monstrose agglomeration (did I mention how you

| People are weird. Nice website though.
