Should I market this as one of ROBLOX's Hardest Obby?

I have been working on an obby that was meant to be unforgiving. However marketing it as one of ROBLOX’s Hardest Obby doesn’t seem like a good tatic. But I feel like it is honest and straight to the point.

Any feedback?

I mean there is alot of obby’s already so go for a different game topic.

you should try marketing it as a very hard obby but i also think you should try to add more unique elements because when i see the thumbnail of your game and tower of hell there is not much of a difference
