Awesome! Love the art style and the chain reactions.
On my first playthrough I did not read the Catalog. Because I thought the viewport scaling was bugged, because a bit of text was shown on the Catalog, but not all of it. To be fair, I did not realise there was an "Open" button. 
When I figured out the rules of the crops it was more fun to figure out the puzzle. From my understanding and experience I felt like the cucumber is really powerful. And for some reason the tomato did not work for me, because I did not see it do something or maybe the chance is very low?
Lastly I like the leaderboard addition,  I want to give it a try to get high on the score!
Well done
