Very good!

Hi, just downloaded and set up on my WP site – works really well. Can I constructively suggest a minor development? As it stands the words you are searching for are always displayed. Can I suggest two options:
1) In the setup an option to not display the the words at all and they need to find them without being prompted to make it a bit harder
2) perhaps tied into this a counter that starts with the number of words they need to find and counts down to success.
3) Could be there is a toggle switch which by default doesn’t show the words but the user can toggle it on to show they words they are looking for – by doing so works for the differing levels that will be doing the challenge

Thanks again for a great plugin!
