Good idea.. something definitely holding it back...
1) a few “hint” pictures are VERY vague... being generous for some of the word choices the questions decide to use.. “the heart of the ‘roman’(hinted with a clock with Roman numerals) ‘empire’(this one was fairly obvious), was located on the ‘territory’(a picture of just some farmland) of this modern country”... that isn’t how anyone talks! The better version should probably read more like: “the modern ‘country’ that was the center of the ‘Roman’ ‘empire’”.
2) Seems like every 4th answer is elephant.. seriously? Thousands of words and you reuse elephant this many times?
3)Lastly.. at least one of their trivia answers is just wrong, Galileo didn’t invent the thermometer, maybe he invented the thermoscope but a very quick google search reveals the answer should be “Santorio”.
It’s ok, but could be much better with minimal work. Change up the words you are using, clean up the grammar and factual errors, make the selected text snippets disappear and not be replaced by more “fake” options, it’s annoying to be further distracted from finding the last word answer, especially when some images are very hard to decipher. I’m giving this app a load of grief, but having said that, it’s decent, not many ads and enough puzzles to keep me busy for a while which is saying something for me.
