This is a blatant and complete rip-off of the mobile game called "Circle".

Unfortunately, you're attempt at plagiarism isn't even well done.

Alright, the game is decent enough for some mindless game play when I'm bored.
Here are my complaints though:
-The lines are very uneven, making the game look weird.
Try to see if you can smooth it out?
-The turns are too sharp.
Going downwards isn't too hard, but when I try to get over the point while going up, it seems like it's a little off. Maybe make it curving instead?
-THE GLITCH
Alright, there's a glitch with the diamonds. The game adds 2000 diamonds every time you click it on the start menu... Just so you know....

A decent idea, but poor execution. The horizontal movement on a vertical screen means that you have virtually no chance to react and you get a game over. Even when you do see it, the ring moves down too slow, and often you'll bump the line. The graphics are overly simple, suffering from no background. I don't have any incentive to collect 250 diamonds to unlock a new shape. If the screen was formatted horizontally, the game might be more tolerable. On the plus side it animates smooth.

Whenever I go up a hill the ring wont come down, resulting in my doom.
