Great idea, that was actually the original concept for the ramps! We uploaded another alpha build where they now function (though the right ramp currently grows all crops rather than just one - I think it may be most balanced to grow more than one random crop but not necessarily all of them). Thanks so much for commenting! We're slowly starting up development again and plan on adding a lot more features to the game. It may take a while but I really like the concept of the game and am determined to not abandon it. :)
