Thank you for your feedback :-)
I developed the game with Firefox browser (it's developed with native HTML, CSS and JavaScript), and only had a short climpse here and there with Chrome browser. Turns out this wasn't a good idea, I missed the critical bug you ran into :-/ The CSS mask effect that "lights" the looting area around the character only applies in Firefox, but not in Chrome.
I will add this important information on the game page now. Sorry for the inconvinience and thank you for reporting this issue .
