Fun little game, I would have liked to see the plants regrow after a time too, also as mentioned by others the platforms break the game a little maybe they can sense when you are on them for too long and crumble away?
I tried to make the trees grow back. (Which they do) But because the game kept crashing it came down to a very limited amount. Also the timer in the top right. Is a timer for when some of the trees will grow back.
