Hi,
thanks for taking the time to try my submission, and also to provide feedback. I completely agree with the sensitivity / bounds of the magnifying glass being less than ideal! I'll make sure I make some time for tweaking these sorts of essential gameplay systems in future submissions.
I also hadn't considered it as a co-op, that could open up some interesting dynamics if you have multiple characters and only the one magnifying glass!
Thanks again for your feedback and co-op suggestion.
Daf
