Hey hey hey! Your graphics look so nice! The concept is really simple and every is so sleek. As mentioned below some of the colours are really similar making it a bit hard to differentiate.
It took me a bit to noticed the links were shrinking, and that's what made the links snap.
I don't think the timer is the best way to approach this either. I think it would 'have been better if you just made a level select screen, instead of having the timer reset you every time.
Hope this helps!
