Awesome feedback! I added a delay to the pop-up win message to make it a little more delightful to view your puzzle.

+ love the idea to share any puzzle with a puzzle link. Will add that in the coming weeks.

Currently leading this project solo, but appreciate the feedback and input!

Hey everyone!

Zach here, as an avid house plant enthusiast I created Photo Synthesis to solve my need of constantly trying to find care instructions for new house plants I was shopping for.

Hope you like it!
