I was sceptical when I saw all the text with instructions, but the game turned out to be simple in a good way, and quite fan. I'd like to see the gameplay tweaked to allow for more collaboration with the AI, rather than just defending it. Maybe the player could harvest the tomatoes and give them to the bot, who would carry them off, and bring back water, or something like that.
All in all a pretty cool game, could be great with some tweaks! Good job!
