Interesting take on spot the difference. The power-ups are a nice way to forgive players for trying out a cookie jar that might have some different quality other than the intended quality. After maybe 6x6 it gets really hard to continue making choices in a logical way. I definitely started risking my biscuits after that. I got lucky finding a few partial biscuit regions before ultimately succumbing to food poisoning. I appreciate the realism. Given infinite cookie jars, I'd eat myself sick too.
