The latest update let you change all graphics of Toilet Tycoon. Yes, you read well: ALL GRAPHICS.
Transform it into a 8-bit game, into a next-gen game (more brown!! more sepia-filter!!), try your own designs ... you can do everything you want!
If you want to know how to do it, it's easy, all pictures are at BMP format and you'll just have to replace them. We have written for you a little how-to just in case:

Have fun modifying Toilet Tycoon!
