Thank you! I was recently playing a real world game with some friends where we had to pick numbers of increasing size in magazines we were reading, trying to one up each other as closely as possible, which is not a great game in and of itself, but we had fun with it. I wanted to make a similar concept for a video game, but have it more measurable somehow, so then I came up with this :) I also love taking something and completely changing the way you look at it - like how in this case an informative article becomes a treasure hunt.
With regards to the bug, I picked only 15 articles (that were the featured articles on Wikipedia that day) to make sure you don't get some crap one, and that was already the end of my 10 hours, so even though I had many more plans of letting you play a couple of rounds and stuff, I just added a reset button and shipped it!
About the decimals, I made it in Firefox which doesn't have the decimals :) I agree they shouldn't be there! I just used the built-in browser preformance measuring tool. Turns out it's not consistent between browsers (inconsistencies between browsers on the web!? Who would have thought!?)
Thank you for the feedback and the questions!
