Hm, I'm trying. Full screen mode seems to shift it but it's somehow covering up for me in Firefox, Chrome, and Safari. Which browser is working on your end?
I'm just using Firefox. I think you might be zoomed in on the webpage - I got a similar issue when I zoomed in
I was finally able to play more of your game due to your comment! I had zoomed out to about 50% to get the covers out of the way. Seriously, just might be something weird on my end. What a great challenging game!
