In case you were wondering, you were right that Alots had to have a heart to produce a baby from mating. They get a heart by being selected first, and then dragging the eggplant over them. Sometimes even that didn't work out because the bounding boxes were bad lol.
Used a custom engine just written using HTML5, Canvas, and raw javascript. We followed you on Twitch!
