Description (written by the developer; not a statement by this register)
Take a journey through one of the most difficult towers on Roblox. Each floor represents a difficulty from Effortless through The Final Difficulty, and it gets harder and harder each floor. How far can you get? THIS IS A MEGACOLLAB! To create a floor, notify us on the community forums telling us what floor you want to build and friend me for access to the build. Players on mobile can build their floors on Obby Creator or Tower Creator and then have us build it as accurate as we can. Hope to see your floors in the tower!

Growth
Growth history is still building. We hold one measurement for this entry. A trend needs at least two, taken days apart — so this will fill in on its own rather than being estimated. We do not publish numbers we have not measured.
