I played and completed Plant Tycoon with all plants and upgrades(but not the bug collection)and i also see the game images in the game folder(i mean, something like programs archive /plant tycoon etc) i saw something.It's named gate2 and fence2; and there are NOT used.
I use version 1.01 windows xp with the message"copyright 2006,2007 by last day of work"

By the time, i don't know how to put the images here,
can you help me?

There are unused images in that folder. Just ignore them.

So that is.
I was wondering something like,
for example, that it was a prize for complete the collections
