Thank you for pointing this out! I can't seem to reproduce it - which link is it that can be click-spammed? I can only hit 'Attempt' once before the option disappears :)
I'm using Chrome on a Windows. I click attempt and it stays a link, when I'm done clicking I have 20+ energy depending. It only works when it says you succeeded and get +2 energy, then you get +2 per click and doesn't unlink until I go out the screen to "survey my work", then it doesn't let me go back. (Which is good)
