A great idea with a nicely polished look and feel. It just needed clearer instructions. "Redact all names, numbers and dates" should be stated very plainly somewhere, rather than phrasing it as "certain names, dates, " etc.
It also wasn't clear that clicking on some words would give me the option to replace them.
- You might consider some sort of visual highlight or dropdown interface on words that are replaceable on the page, with a few red herrings (words that are replaceable but should be left alone) sprinkled in so it's not too easy.
- The option to unredact something would be good for players who accidentally redact a word when they actually thought they were going to replace. I was kind of scared to click on words I wanted to replace, in case it would permanently redact them.
- Maybe replacing a word should be done with a different control than redacting, e.g. a right click instead of left, making it harmless if players right click a word and nothing happens.
Really love the concept and would be cool to see it expanded!
