I love your game, but I think there are a couple of things missing. The first one is speeding the game up, because the game closes after the computer goes into sleep mode. Another feature that I think would be nice to see in the game is making spores more visible. After zooming out you can not see the spores on smaller screens. The last thing that would help out experimenting in the game is an option of deleting a specific mold. I like your game overall and I just wanted to give you a couple ideas
